For those of you who do not know, the recently released Halo Reach has a level and game-type making mode called Forge World. In this you are able to make any number of this, including modes that make it not play like an First Person Shooter at all.
A Super Monkey Ball fan has taken it upon himself to remake the Monkey Target minigame where you have to jump off of a ramp and aim yourself and hit the target if possible and try to get as many points. Obviously it is nowhere near as good as the real thing, but it is great to see fans take so much time to remake something like this! There are bound to be tons of SEGA themed variants in Forge World by now, so send a link if you see any!
