someone will now point out that it's RIGHT THERE
It's right there, over the wall you can't get past.
Gorillas and Bananabombs: Not only do they both have a wikipedia entry, there's also flash-based versions of those on the web. Including the original sound.
Now that's just neat. Oh I remember being a curious 10 year old opening gorillas.bas on his very first DOS computer, and to my surprise the source was actually readable unlike all the other applications I tried to open, searching hopelessly for the source, figuring out how the hell programming worked by adding more random characters to the gibberish. Not much time later I clicked and dragged together a little adventure game. So was my first experience with programming.
But I'm straying off.
OH CRAP I HIT IT WITH ANGLE 80, SPEED 120!
