Buggy, on terrain, with texturing and shadows...

A closer look at the buggy. Notice the full double-wishbone suspension, ball-jointed front end, and Ackerman link steering. The spherical tires are necessitated by a limitation in the collision-detection library - they look a bit silly, but they work just fine. Hopefully that won't be necessary for long.

First screenshot of the new terrain feature.
(The shadows you see above came later.)

A simulated Segway. The platform balances front-to-rear with motors on the wheels. The big red "nose" is actually a slider joint that moves the rider's head and upper body forward and backward, which tips the whole thing forward and backward, which causes the motors to kick in... Steering is done by varying the speed of each wheel, and the rider can be leaned side-to-side to aid cornering. It just occurred to me that leaning should probably be what causes steering, not the other way around... I'll have to try that some time.
