This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

RugWorld (C) B.Moseley Nov 1990 ******************************* RugWorld is a cellular automaton programmed in ARM code for the Archimedes. It operates on an 80 x 64 grid of 'cells', each of which can be in 256 different states - represented by different colours. Once started, the rugs will swirl with patterns of constantly changing and interacting colour competing for space. The program will load up any 80x64 Mode 13 sprite, from the <Rugs$Dir> directory (by default inside the application itself). Three demonstration rugs are supplied - these may be edited in !Paint if desired. Once the program is run, a catalogue of the Rug directory will be shown & filename asked for. The user is then prompted for 2 numbers. The first is an increment to be added to the average of the neighbours of any cell. The second is a mask which is ANDed to the result. (A value of 255 leaves the average/increment unchanged). The rug will then be loaded and animated. Press ESCAPE to restart. Some values to try: Inc 1,2,3,255,0 Msk 255,63,31,15 Have Fun! P.S. Two versions of the program are included on the disc. In one - !RugWldG, the cells are separated by a black grid. This, in my oppinion gives an enhanced effect.
