I tried 3 different searches and didn't find a similar topic... I hope it's not a dupe.

I don't recall there ever being a demo thread for Apple II. Otherwise I would have marked it for following.
Unfortunately I never did recover all my GRAPHDB demo disks my buddies and I whipped up back in the day. GRAPHDB was just an arbitrary name I made up for a series of disks and means nothing. It probably did to my childhood mind, but damned if I remember what! The disks I did find were in the garage exposed for years. So that's that. Most were demos of animated art and geometry, not necessarily demo-demo material like the scene groups or anything. Maybe with a new coating and lubrication layer they might be readable. IDK.
Hell, the Apple II is disadvantaged when it comes to demos. You can't really "push" its hardware or uncover hidden tricks or use the hardware in unintentional ways when it comes to graphics and sound. Everything is rather finite and rigid for A/V output. There's simply "not enough". Unlike the TIA or custom chips in other 8-bit rigs. 30 and 40 years later we're still finding out how to trick those mystery circuits into doing something they weren't designed to do. Or thought of for. I swear the TIA and brethren are mixed signal, and that makes for a more organic flow. More ambiguity.
The creativity process in the Apple II seems different than most micros that followed it. You have an array of memory and that's basically it. There's a lot of hidden magic and ingenuity in the copy-protection & de-protection camp. And wouldn't you know it? That's were there's some analog circuitry! But that's a whole other field outside and away from demos.

Some people have taken disks out of the original sleeve, cleaned them (not sure how) and inserted them in new sleeves.
That's the easy part. Cut, fold, tear, whatever, however. Wash with soap and water. Plain water, sometimes a bit of alcohol and water. All depends on the contaminant. Sometimes a short soak. OR you can use specialized chlorofluorhydrocarbon based cleaners. I find a damp Q-Tip good for spot-cleaning fungus.
TRIVIA: The bare disk substrate will work in a drive if you insert it and align it carefully. It will work for a long time because it doesn't really rub against anything except the head and pressure pads.

Is this open for ALL Apple ][ Demos?
VeCaves II- Eat to survive (very early concept with Mockingboard support). - Spacebar is all you need to know.
