[design]

I have a similar engine up at http://joelcalifa.com/colors

Mine can also do colors like "banana" or "bubblegum". Pretty simple to put together actually. Rather than manually putting together a list of colors, I just use the ColourLovers API. You can also use up and down arrows to move between results or the return key to "make a poem," which I fully agree was a weird feature to add.
