More a showcase than an actual game, this Super Mario Kart clone lets you race forever and ever on a limited selection of Mario Kart courses against a few of the original Super Mario Kart characters (Mario, Luigi and Princess Peach).

The canvas element was used heavily in this game to rotate, stretch and position slices of the map to simulate perspective. The technique is similar to the "Mode 7" graphics mode that was used on the SNES to create this and other effects. A bit of embedded MIDI music is thrown in for good measure. A few more technical details are available in this blog post.
