Here's an interesting concept from designer Brian Matanda: it's called Timeless Capture, and it wants you to be a little more dang sentimental about your photos. Timeless Capture automatically pushes your snaps to a married photo frame, so your memories are always on display. In fact, that's the only way to view them.
The camera half of the equation as no LCD viewer of its own. That's not all that's going on here, either. The camera design also calls for a low amount of storage, forcing you to bring it near enough the frame that it'll push your photos over wirelessly. The hope here is that — in this post-Instagram, filter everything world — you'll take a little more care capturing your photos and they'll be a little more special for it, popping up on the companion frame.
Matanda, a design student at the University of Dundee in Scotland, has a series of blog entries covering how he built the camera, if you're curious.
