Jim's Shareware
 
All the software listed here was written by Jim Bumgardner, and some of it includes the source code. It is mostly free. More recent software (mostly for Windows) is at the top, and older software (mostly for Macintosh) is at the bottom.

Note: Actually, ALL this stuff is pretty ancient. I haven't put new software on here in about 4 years, and I'm back on a Mac now... jbum, march 2008

I hope you enjoy the software!

Mandel Zoom (Windows) is a beta version of a new fractal explorer I am working on. Unlike many Fractal programs, Mandel Zoom will enable you to zoom in and out of the Mandelbrot set in real time. The program can produce a bewildering variety of beautiful images and is quite fun to play with. Check it out!

Cheese Toast III: Attack of the Scones (Windows) is a new version of Cheese Toast that I have been working on more recently (2003-2004). This version takes advantage of 3D acceleration on modern graphics cards and features new graphics and sounds.

 
Plywood, version 1.7.2 (for Windows) is the latest version of my home-grown computer chess program. It plays against humans on the Free Internet Chess Server and has a FICS rating of about 2150 (not that great as chess engines go, but far better than my own 1000). If you drop by FICS, say hi to Plywood (or jbum) - I might be online watching plywood's games.

If you'd like to run Plywood on your own computer, you'll also need a copy of Winboard (shown at left), which is a standard interface for running chess-engines and you will have to figure out the arcane process of reconfiguring Winboard (hint: edit the winboard.ini file). If this sounds complicated, I suggest you take up checkers.

In 2001, I was playing a lot with Renderman, using the (once) free BMRT renderer. Some of my Renderman shaders can be downloaded at renderman.org.

I also wrote some OpenGL screen-savers. These run on Windows and require a reasonably fast machine (>= 300 Mhz) with a graphics accelerator card. To install these, drop them in your "System" or "System32" folder (where your other screen-savers are kept.

Sproinks (for Windows) may be the prettiest OpenGL screensaver I've done to date. It uses layered noise and radial blur to get some interesting plasma-like effects. It looks sort of like a cross between a tie-dye shirt and the aurora borealis.

Space Rangers (for Windows) is an OpenGL screen saver that shows a busy highway in space, as imagined in the 1950s. Cigar shaped rockets, wobbly planets, and a flying saucer. Space Rangers periodically displays in black and white with simulated film dirt.

Yggdrasil (for Windows) is an OpenGL screen saver that depicts the mystical earth-tree of Norse myth. Yggdrasil's branches support the heavens, and its roots go into the underworld. Yggdrasil acts like a clock - it's lighting is based on you local time. Yggdrasil also brings CPUs to their knees.

More of my screensavers are available at KRAZYDAD (my new website)...

Pixel Magic 1.0a (for Macintosh) is a stand-alone version of my Photoshop filter "Expression" (that is photoshop is no longer required!). Think of it as an exploratory graphics program for the mathematically literate. It creates images by computing the results of mathematical expressions which you supply. It can be used to create some extremely interesting and beautiful special effects such as Fractal Zooms, animated clouds and many others. I use it mostly to create animated textures for 3D modeling but it has a number of other uses.

This type of software is perhaps too artistic for mathematicians, and too mathematical for artists. If this description intrigues you, then check it out!

I also have a Windows version, e-mail me if you want it.

Syd (formerly SoftSynth) (for Windows and Macintosh) is a music synthesis program in which you can "patch" modules together with patch cords to produce interesting sounds. It is available for both Mac and Windows.

 I wrote Syd so I could reproduce some of the sounds produced by the Buchla 200 analog synthesizer I used to play with at CalArts in the early 80's. It has since evolved into an interesting computer-music tool in its own right.

Source code available upon request.


 
Orville 1.1 (Macintosh) is my favorite parlor trick for unsuspecting strangers. Orville makes your computer act as an assistant for a mysterious demonstration of Artificial Intelligence (in other words, "Mentalism" with fancy new packaging). Orville uses some old tricks from Mentalism routines from the turn of the century and is quite effective at fooling unsuspecting victims that your computer can read their minds. The documentation explains how to operate it and how the tricks work. A little practice is required. Use Orville and get that AI research grant you've been wanting! The Source Code is also available.

Here's a Windows version of Orville (not as fully featured) for you to check out!

Here's a Palm Pilot version of Orville (nearly brain-dead) for you to check out!

And here's a similar trick I wrote that works using plain-old HTML. Have fun!


 

NOTE: All the programs below this point are primarily here for HISTORICAL INTEREST and won't run on newer Macintoshes.

 
Hypnoticon (Macintosh) converts MIDI data to animated graphics in real time. It can produce an interesting "light show" as you play a MIDI instrument. The program pays attention to such musical information as pitch, velocity, note durations and harmony and converts this information to graphical information such as color, shape, size and motion. Currently the program has a number of built-in graphical effects, such as "rain drops", "stained glass", and "flying notes". Apple's MIDI Manager is required. This program is fairly old and may not run on newer Macs.
 
CD+G Player (Macintosh) was a program which allowed you to play and see compact discs in the now hard-to-find CD+G format, an unusual hybrid of CD audio and graphics which is still used to make Karaoke discs. If you have any CD+G discs, here's your chance to see the (low resolution and slugglish) graphics they contain! A list of known CD+G titles is included. (Ancient Macs with Apple SCSI CD-ROM players only!).

If you're interested in the CD+G format, here's a document that explains how I wrote the program and if you're really a masochist here's the source code.

Update: David Cotter is working on an OS X compatible CD+G Player, called KTunes, which incorporates some of my old source code. Check it out!

 
Cheese Toast (Macintosh) is a tongue-in-cheek asteroids-like game I wrote back in 1991 to learn a little about sprite programming. If you look really closely, you'll see my head (circa 1991 with a little more hair!) floating around in space. Source code is included.

 
Son of Cheese Toast (Macintosh) is a sequel to Cheese Toast that I worked on in 1995. It has better graphics, larger sprites, and some new bad guys, including the evil english muffin twins, Nook and Cranny. Source code is not included.

 
Cheese Toast III: Attack of the Scones (Windows) is a new version of Cheese Toast that I have been working on more recently (2003-2004). This version takes advantage of 3D acceleration on modern graphics cards and features new graphics and sounds.

 
HexEdit 1.0.7 (Macintosh - see below for latest version) is a programmer's Hex editor - for viewing and editing files in a hexdump format. I have found it to be indispensible in my work, primarily as a tool for analysing the contents of binary files. Also occasionally useful for those Internet downloads you can't unpack and you want to figure out "what the hell IS this thing???" Source code is included.

Note: The OUT OF DATE version offered here is the last version of HexEdit that I worked on personally. In recent years, other programmers (esp. Lane Roathe and Nick Shanks) have taken up the mantle and produced enhanced versions which add features, fix bugs, and run in a more stable manner on more recent versions of Mac OS. You can find the latest version of HexEdit (1.7.5 at last check) here.

 
Photoshop Expression (Macintosh) is a multi-purpose PhotoShop filter for the mathematically literate. It creates images by computing the results of mathematical expressions (thus the name) which you supply. It can be used to create some extremely interesting and beautiful special effects such as Fractal Zooms, animated clouds and many others. I use it mostly to create animated textures for 3D modeling but it has a number of other uses. This program is perhaps too artistic for mathematicians, and too mathematical for artists. If this description intrigues you, then check it out!

Here's the 3.0b version for 68k macs and here's the 3.1 version for PowerMacs.

 
Softimage Plugin (Macintosh) is a Photoshop filter for importing and exporting images from the Softimage format. A useful utility for those of you forced to use those expensive boat anchor SGI machines. :)

 
That's it for now! If there's something else you'd like to see here, send me some e-mail.
