Backstory: Digital photo frames never really took off, they're a fun novelty but I've never seen them featured at a friend's house. Producing a paperwhite like image rather than a bright LCD screen may be the trick to further adoption.

The Idea: A large scale digital photo frame.

Deep Dive: You would have to find how to source and produce a larger version of the paperwhite style screen, less glare, brightness and looks closer to an actual piece of paper. You would then have to build a prototype frame and see if anyone would purchase.

Validation: Digital frames already exist, this would improve them.

Monetization: Another ecommerce play, you have to watch your margins.
