Current projects available from Crazy Wizard Software

1. Rainbow Labyrinths, a colourful demo written in Berkeley Logo showing a series fascinating self-avoiding curves.
2. Cellular automata, A small program in Basic showing elementary cellular automata
3. Pegasus public beta, an emulator for the Intel 8080 (including console I/O, four virtual floppy drives of 250KB, emulated tape interface, adjustable speed), together with an abandonware library containing the CP/M 2.2 disk operating system, several versions of Basic, and seven games.
4. Roger, a demo showing a colourful rendition of Penrose tilings of the P1 type.

News

• 24 December, 2021: a new demo, Roger, has been added. Enjoy!
• 16 December, 2021: a new public beta of Pegasus has been released, version 0.98.1. Furthermore, today is the official announcement that Mad Wizard Software will henceforth be called Crazy Wizard Software.

A small tribute

The program below is a little in memoriam to my father, Dik T. Winter (1945&emdash;2009), who once wrote the following program in 160 bytes of C to compute the first 800 digits of pi:

int a=10000,b,c=2800,d,e,f[2801],g;main(){for(;b-c;)f[b++]=a/5;
for(;d=0,g=c*2;c-=14,printf("%.4d",e+d/a),e=d%a)for(b=c;d+=f[b]*a,
f[b]=d%--g,d/=g--,--b;d*=b);}

For more information on the algorithm that he used, including an analysis of the program, see e.g. this page hosted at Stanford University.

Happy computing!
