Once again, it's time for our collaboration with the always fascinating What Is It? Blog. Do you know what the pictured item is? Or can you make an amusing wild guess?

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. Two winners: the first correct guess and the funniest (albeit ultimately wrong) guess will win T-shirt 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?

Update: the mystery object is an inkwell. Congratulations to Anker, who had the correct answer right off. The funny answer award goes to Straight_Flush, who declared this to be a small hadron collider! Both win t-shirts from the NeatoShop. We had a lot of imaginative answers this week, some x-rated, so you should go read them all!
