Quartzeroids and SciCalc . Download them, they are both good. If you need clone of Minesweeper, or a complete and integrated implementation of Zernike moments and neural networks for image recognition, both of which are written in CodeWarrior for OS 9, then email me.
Extra points go to anyone who actually knows what Zernike moments are.
If you have any questions or comments about any of the programs I have written, please email me. I don't include a proper link, but automated web crawlers which spam any email address they find really piss me off. Programming resources found on this page are the property of Matt Gallagher unless otherwise stated. The current version is a little slow on some machines because it handle updates inefficiently and Quartz doesn't accelerate updates which overlap the edge of the screen. A faster version will be available soon.
