Well the dust has settled from Frame 3, and now it appears we have crumbs for Frame 4. DCPB has updated with a pic of the words "Wall Street / Larchmont" in a sort of normal font with pixels and specks falling off it.
A quick Google search got me the lame theory of the Larchmont Hotel in New York, but a far better idea is on LostARGs where there's a bake shop company called Crumbs that has shops in Larchmont, California and on Wall Street, New York. Clue or not, I'm enjoying looking at the pictures of some buff cupcakes. We'll see how things develop, and keep a look out for more clues.
