I also regret that I didn't find the time/energy to create my own entry. It's nice to see, however, that some people had similar ideas (even if they were implemented much better than I could have done). I could, of course, try to quickly put something together, but after looking at the other entries, that doesn't seem like the best approach. So, maybe next time.
Oh dear, I already included you in the list of participants. I'll have to change that quickly.
