In college I did a project where I added a speed of light delay to a game of Asteroids. I didn't implement a proper Lorentz transform per se, but the effect was still pretty cool. Just for fun I added some faster than light particles and FTL jumps and wormholes. Notable side effects: FTL particles appear as if they teleported to a location then split in half and leave in two directions. You can sometimes see an object leave a wormhole and then enter it. When you FTL jump, you can see yourself from a few moments ago about to FTL jump. If you fire your laser and then FTL jump in front of your laser, you're in for a bad day.
