Loved Pixel toy for many many years on my old Macs. Then my job suddenly became more stressful and I lost track of Pixel Toy (v 1.1). Until today. Found it again on an old floppy, and it worked perfectly on our old old Macs and our new Macs. No installation, no crashes, no problems AT ALL. It is just pure fun. We use it as a screen display or as an elegant diversion for students who come to send a fax and have to wait a couple of minutes for a confirmation to print out. They can change any of the settings, turn on ALL the options if they want to. Can't possibly hurt it. But my favorite feature...you can resize the window to any size or shape, change any of the options one right after the other and PIXEL TOY JUST WILL NOT STOP. No screen redraw AT ALL. Doesn't even need to catch it's breath. PIXEL TOY is just a magnificent little program that harms no one and makes your day a little nicer. (And I only have the 1.1v. I can't wait to play with the new one!
