DIY 3x4 Polaroid TLR kit on Kickstarter
I've been following the development of this TLR camera on Flickr for a little while, and it's finally made it to near production stage, so sharing the information.
It's a DIY kit to make a TLR out of a Mamiya 105/3.5 lens (made for Mamiya C series TLRs) that can take 3x4 polaroid backs as well as various Graflex roll-film backs up to 6x9. The 105 lens covers 6x9 fine and covers most of 3x4.
FYI, I immediately pledged for the "Deluxe" Kit
