A few years back I was going to post a few “geeky mailbox” designs but I got sidetracked and completely forgot about them. I recently played Sonic The Hedgehog and remembered this particular design using the checkpoint (aka “Star Post”) from the game.
This design is for my American neighbors, seeing as Canada’s residential mailboxes are being put out to pasture. Canada Post is run by a bunch of hosers, eh!
Initially I thought the Star Post would be cool for a lamp or outdoor lamp post design, however the bulb’s red and blue colors aren’t exactly friendly for illumination. I do think it would be awesome for a beer tap or gear shifter though.

What about making the shell semi-translucent white, and using LEDs to make it red, then when mail is deposited, it could even flash red and yellow like a triggered checkpoint in the game.
Maybe not for an actual mailbox, but I could see it in a home. If made slightly larger, it could be a sort of clean clothes hamper for a kid.
You should totally do a Pokestop Mailbox
