There was a few articles going around about the company that built the vehicles for Racing Legends. I've also seen a few videos getting posted of the ride footage. I worked on the first scene, the Rome one, and the final futuristic one. It's fun to see the final footage in context. Apparently in additional to the vehicles moving, they also have "4D" effects like wind and water mist during the ride. Pretty fun to get an idea of the omni theater setup.
I also ran across some promotional posters that a design company produced for Mousetrappe for use in the attractions. It was a series of travel posters for many of the areas visited over the course of the attractions. It's just fun to see all the peripheral design that goes on with any attraction.
