I’m sure that you like the Optimus Maximus keyboard, but if you don’t have enough cash to buy then the alternative is the Luxeed Dynamic Pixel LED Keyboard. The colored keyboard is based on 430 LEDs which look very cool and you can customize them with an included Windows software.
The Luxeed Dynamic Pixel LED Keyboard is available at ThinkGeek for a price of $199.99 and it’s available in black or white. Also, for extra $34.99 you can buy a numeric keypad which unfortunately doesn’t feature any colored LEDs. Check out the video below and the the Luxeed keyboard in action!
