Thanks! I wanted to make a card that contained recursion (what can I say -- I'm easily suggestible. Recursion was one of the topics on BoingBoing this morning). I found a suitable drawing in Conchita's photobucket account, figured out how to make the contents of the flask recursive, added the text and a few special effects, and called it good. The only thing that would have made me happier would have been using my own drawing Snape in his laboratory, but considering I can barely draw stick figures, that just wasn't possible.
