Julldozer created an amazingly clever digital sundial ("Cadran Solaire Numérique") that precomputes the angle of the sun throughout the day and uses those computations to make hundreds of precise holes calibrated to cast a shadow displaying the present time.

The whole thing is open source hardware, with 3D files on Thingiverse; but if you want to buy a premade one, Mojotpix will sell you one for $80.
