What better subject for a t-shirt than an Adventure Time/Katamari Damacy mashup?

Bitcoins? Pah. Warren Ellis and Diesel Sweeties have teamed up to offer a limited edition Baconcoin tee -- available until May 14 -- that finally proposes a currency based on fat, nitrites, and salt, as nature intended.

I'm at LAX as I type this, heading home from a great family spring break in LA that culminated with a trip to Disneyland. While I was at the Mouse, I happened upon this killer Haunted Mansion t-shirt, which wasn't available in my size at first, but later got re-stocked. I'm wearing it now. it is awesome Alas, it appears to be a park-only item (neener-neener), though you can always try Disneyland Deliv-EARS (and yes, it glows in the dark).

PS: I also met a Haunted Mansion cast-member whose no-foolin' hometown was Purgatory.

ThinkGeek's done a Tenth Doctor "costume tee" that's pretty great. I'm assuming that all that detail is silk-screened with fool-the-eye shadows, and not actual additional material sewn onto the shirt's front (though that would be megaboss and someone should totally make it).

A pair of most excellent copyfighter tees are now available from Techdirt's store. They've revived their classic DMCA notice/YouTube shirt, and added a fab "THIS T-SHIRT HAS BEEN SEIZED" ICE tee that has to be sen at full size to be fully appreciated. $29 each.

(Thanks, Mike!)
