The trouble with processing

A simple thing you’d think right? All I wanted to do was to embed and existing sketch into a post. I’ve done it before, but today, no, no way at all. It may be of course that it is because it is using the minimum library for synthesis, but I don’t know for sure.

The sketch I’m trying to embed is here, and the reason for trying is because I only just found the code again and decided I might try and do something more with it. That was foolish wasn’t it!
