Jayenkai	Circle Patterns Yesterday, Pakz retweeted this tweet.. Linkage It shows a pattern generator that uses circles spinning to draw a pattern on the screen, a bit like the cogs in a spirograph. I tried making my own, but mushy-maths-brain ATM made it a bit shit by comparison. Perhaps you could make something that's a little bit better? // Spirography // by Jayenkai // Created 2023/6/20 // GotoJSE.com/7wjxVprZ.BAS // One // Select a few cogs of different sizes. // Tap inside the rings to change their size, or outside to change their link-position // Grey = the cog is disabled // Two // Click Play, and watch the swirls. You can use the Fast Forward button to speed it up. // Three // Stop, then take a screenshot of your lovely pattern with the ; key. // Extra // Turn the variance off or on for added ... ... variance!
