Inspired by Marty McFly's colorful cap in Back to the Future II.

Check out the Back to the Future II collection!

The color-shifting effects shown in the video require some simple additions/enhancements to the Source SDK. If you'd like to see this hat with similar effects added to the game, use your preferred communication method (leave a comment, create a thread, send an angry letter...), to ask Valve to integrate my SDK changes to TF2:

Github Pull Request 315[github.com]
Github Pull Request 316[github.com]

If the changes are added, the final effect would likely be a toned down version of the effect in the video.
