Well... I've just put the finishing touches on Lobster Petting 126.96.36.199... It's a Universal Binary, about 4.5 MB zipped, and runs fine in 10.4.8. All the same Lobster Petting features are there: a lobster, claws, sound... You know. Made entirely in RealBasic, it's a little large, but it doesn't crash! It is of course available from my own website.
I also started work on Zoltan! Which will prove to be even more bizarre and interesting than Lobster Petting. More updates later!
