@SMcNeill do remember where/when the one I posted of your came from?
It seems recent to my memory, oh let me check copy date in Windows...

I would guess it came from the original forums that Galleon had up about 10 years ago, or more. Those were back in the days when we were playing around with chat bots and such in IRC, and that's what this used to store and retrieve the highscores for people. It's oooooold. Good thing I'm not!

bplus@: yeah, I was going to use the flash stuff for a special effect, but never really got there. For now it just marks cells that doubled so they can all grow in at the same time. Not really that important.
Hey I didn’t remember Steve made one too. Looks solid.
