Nice :)

Cute.  Should have Don Ho's "Tiny Bubbles" playing in the background.

Whooooooa! Your mods never disappoint, bplus!

[johnno56]

Now where have I seen this program before? It looks familiar. Can't quite put my finger on it... LOL
Text or not. It still looks impressive. Nicely done!

[bplus]

Thanks guys, yeah new use for old code. The random letters from "kelp" worked really nice for water effect.
