A Chemical Jigsaw Puzzle
Based on an idea by Omer Roucoux
Don't know how combining powers work?
In 1978, Omer Roucoux published this chemical jigsaw puzzle. It is available here in two parts, as a GIF and the original DrawFile version (for RISC OS), which you can download separately. Best results are obtained from the original.
