I came up with the Mouse Kaleidoscope idea a long time ago, but waited a while to actually make it in Flash. I recently decided to put it on Newgrounds. It has 297 mice. This is my first thing on Newgrounds, so I hope I'm not doing anything catastrophically wrong right now. Sorry if the logo is too big and distracting in the back, I just thought I should put it somewhere. Anyway, I hope that the Mouse Kaleidoscope will keep you occupied for hours! Maybe not hours. Try to spend at least a few seconds on it, though.
Like I said, I'm new here, so I hope it's not rude to put my website, because that's what I'm doing right here: http://unknownthingamabob .com/
