The Pentax Rainbow K-x is so rad, I don't know where to begin. Designed in collaboration with Tower Records, they may seem a bit nauseating (according to Wired.com), but I think something that colors your world like this can only bring happiness.
Sadly, there is no gold at the end of this Pentax Rainbow K-x. Instead you'll have to dish out $810. Yet it might be worth it considering that only 1000 were made in total. Identical to the standard K-x model, the colorful versions, I must say, make a big, big difference.
