In a way that Apple would have never imagined, $700 Mac Pro wheels were used to create an actual skateboard by a YouTuber and the results were impressive.

For those keeping count, Mac Pro wheels actually cost $400 if you order them during the build-to-order process. However, if you want to buy and attach them to your Mac Pro later, they cost $700. Unbox Therapy got the wheels and created a less than average skateboard which did not practically work. This inspired Braille Skateboarding, who took it seriously and created an actual skateboard with it.
