K'Nex is to launch a roller coaster set later in the year that comes complete with webcam so you can catch all the action on video as if you were riding it yourself.

The giant set, which K'nex makers Tomy, says will take you a number of hours to build, features a motor driven pulley system that sees your roller coaster car dragged up high before being let to hurtle down through a number of banks and turns and the obligatory loop de loop.

Once the run has been finished you can either watch it go around again, or whip it off and plug the "car" into your computer via the accompanying USB cable. 

Footage of your ride, which will be shot at 640 x 480, can then be shared with the rest of the world via YouTube.
