I was messing around with the HTML5 canvas element this morning, and I came up with something kind of fun. It’s basically a puzzle built with a series of rotating concentric circles that you can drag. Here’s a screenshot: Check it out. Keep in mind that I didn’t add any logic to confirm that you’ve [...]
