There used to be a UT-clan called "TnT" with a stylized logo of that explosive on a window in the front & back of the torso...
... but near as I know they're gone now and I thought something better could go in those windows.
Instead of better though, I opted for silly.
Team colors fairly standard, but the icons on the front & back also change for each team color.
Enjoy!
