Son of Cheese Toast 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. HexEdit 1.0.7 is a Macintosh 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.
Source code is included.
You can find more these more recent versions of HexEdit here and here . Photoshop Expression is a multi-purpose PhotoShop filter for the mathematically literate. 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.
