If you're looking for a more unique flash drive, or possibly one that could be easily hidden in plain sight from would-be data thieves. Check out this Lego flash drive.
It seems that the people over at Zip Zip saw enough of those DIY projects where people were converting old Lego bricks into flash drives that they decided to mass produce them.
They come in a variety of colors, but just one size. These 1GB drives come in yellow, red, green, black, white and blue. I'm not sure if they are interlocking, I've got an email out to Zip Zip on that one. They are a little more expensive than most other drives, but you can't put a price on nostalgia. But if I had to I'd say the price was around $49.
