The coolers I've seen have translucent doors (see comment above), so the game wouldn't be super clear. The Walgreens coolers could do it but I presume you're joking as it would have no concrete benefits over putting a normal screen in front of a bunch of coolers (or even projecting onto some white coolers).
The only real benefit would be getting a large screen out of stupid VC money.
These things are obviously a solution in search of a problem. MAYBE it would make sense on the front of a vending machine (because then you could hide the mechanics and perhaps get them more dense).
