Bit miffed it didn't accept fruit... think pears? Otherwise, good grid.

Ah, darn. Very good point. Was tunnel-visioning a little bit there. I'd change it if I could...

Glad you liked it.

Another nudge here for 'fruit' rather than just apple, pears and tomatoes are others that would qualify off the top of me head. Feel slightly swindled by 'energy' not being accepted for the thermal group as well, but that might just be sour grapes (ah, there's another one)

It is frustrating that there's no edit function... however, we all make mistakes!

A good selection of categories, nice crossover on the 'cell' group.
