We've just released a 30 day trial for our new children's web browser, BumperCar. The demo is not crippled in any way, but will overlay the word "Trial" upon all browser windows. Also, this demo does not include any of the full version's bundled games.
The download clocks in at 14.51 MB, and is available for OS X 10.2.8 or 10.3.X. BumperCar is available for order from the Freeverse Store or is available from fine Mac software retailers everywhere.
