I saw this wonderful goldsprints visualization on Tumblr the other day:
It looks like they competed over a set time, and riding at greater speeds "unlocked" different visual effects and riding environments on the screen.
The site for the people at Red Paper Heart who created this says that they built it over OpenSprints. It's a far cry from the default Opensprints interface.
If somebody wants to help me develop something like this, if somebody ever wants to put a more refined system like this on the market for purchase, I'd be very, very interested.
