Im starting to play around with a 3d aquarium in flash... which is pretty cool using away3d, some low poly fish and some nice backgrounds. Its starting to look nice (demo soon)

Anyways... Im thinking I'd like to make it into a game... currently its pitched at the feed, grow, sell idea where you can upgrade to bigger fish, more of them etc etc Im thinking it might be fun on facebook or something....

But I am sure there are other cool aquatic game ideas out there that I'm missing so I'm throwing out a blank canvas board for ideas

is a VERY rough start just to see what some fish would look like. The movement hasnt been done yet and only the angle fish has been properly animated.

Im certainly thinking a hungry fish game in 3d could be fun too
