Not quite, but pretty close. It’s the Luxeed LED Multicolored Keyboard out of Korea. You can program it to change colors, stay certain colors to suit your mood and you can create your own color patterns. The Luxeed USB keyboards are available in a white back-lit version (KRW 118,800 / $127 USD) and a black back-lit version (KRW 125,600 / $134 USD), where the keys stay black and only the letters change colors. I’m really considering getting one of these and I don’t even use a desktop. They’re on sale right now at ThinkGeek.
