I want to build something, Ideas?

Question

I am looking for something that is not impossible to make, and something that Dad would find useful for fathers day.

I want to make it myself because i think the significance will be better than if I go to the store and buy it.

All your idea's would be awesome

Make a birdhouse that looks like a mailbox.  Write "Air Mail" on the side of it.  Mount it on a tall pole in the front yard near your regular mailbox.
