is an interesting little mini-game that was originally coded in two days by Joseph White for the Ludum Dare 48 hour competition.
Instructions from the readme file are as follows.
Use the cursor keys to turn left and right. Press space to fork the sprout. The longer you hold down space, the greater the angle becomes. Hold down the up cursor key to go faster.
To complete each level, you must collect all of the leaf and flower pickups without having any shoots left over. You must not let the shoots crash into each other, or the side of the screen.
Recently updated to version 1.02 to include more levels. Available for the Mac as well.
