Mine's a portal-themed Vortex Race 2 75% keyboard with Cherry MX Browns and white backlighting:
Number Keys, Tab, Caps Lock, Shift and Win key are portal-themed.
Arrow keys, Enter, Right Shift and End

With Backlighting:
The keycaps were custom printed from wasdkeyboards.com. Since the layout of the Race 2 is non-standard, I had to sacrifice the modifier keys (Ctrl, Win, Alt) to have the arrow keys + the right shift and end printed. To compensate for that, I replaced them with some MKC metal modifiers from banggood.com.
You'll see that I also have a set of metal WASD keycaps made from MKC, also from banggood.com.
