Wallpaper was written in THINK C and MPW C and assembly, and debugged with the aid of Mr. Bus Error, HeapQC, Bo3b Johnson's Zap utility, and too much MacsBug. Big thanks to Apple's Developer Technical Support (DTS) staff for their help with gnarly QuickDraw problems. Thanks also to Andrew Welch for his handy sound and offscreen-graphics code, and to Ron Risley for coding the pattern preview and more.
