The mysterious Iamamiwhoami viral campaign continues–and this time, it’s tangible.

The writer over at MTV studios just received a completely anonymous package in the mail. Inside? A lock of blonde hair, some pieces of tree, and a puzzle containing pictures of the animals found at the end of each video.

Current guesses go to The Golden Filter, Kerli, and Margaret Berger, although it would seem unlikely that the latter would be sending packages from distant lands.

OR IS IT SADAKO FROM RINGU? The world may never know.
