It is once again time for our collaboration with the always amusing What Is It? Blog. This week's contest is a little different. To be honest, we don't know what it is! It looks like a case, but no one knows for sure what it is for. Don't let that stop you from guessing.

Place your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. Post no URLs or weblinks, as doing so will forfeit your entry. We'll select two winners with the funniest and/or most imaginative guesses to win T-shirts from the NeatoShop.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize, okay? May we suggest the Science T-Shirt, Funny T-Shirt and Artist-Designed T-Shirts?

Be sure to check out the What Is It? Blog. Let your imagination run wild, and good luck!

Update: The most imaginative guess was from arvana, who wrote a somewhat involved story insinuating that this case could hold the Prometheus Drive which would save the world's energy problems if it hadn't gone into the river (you really should read the whole thing). The funniest was when jjent567 declared the case was "fer me rat stompin' peg leg...".
