Weekly Time Waster : Fig 8.

Figure 8 is an interesting (and very addictive!) web game.  The point of the game is to control a bicycle (using the arrow keys) while avoiding any and all black lines. This includes text, scenery, anything!

Fig. 8 is very easy to pick up and gets gradually difficult.  Save points along the way allow you to save your progress by circling them with your bike.  There are also score indicators as you go along.  The art is plain black and white, but adds the feel of history.  You  seamlessly traverse through a series of architectural drawings, each more difficult then the last.
