Penumbra with totally 3D Graphics?

[Thaliur]

Besides, I'm not sure if that would really work...
Basically, there are three popular ways to create 3D images:
coloured glasses, shutter glasses and polarised glasses with cross-projection (best of the glasses).
(there are some "natural" 3D screens that use prismatic shapes, but they're quite expensive and rare)

Shutter glasses won't work as desired, since TFT screens are very common by now, and the way they work will most likely render the shutter glasses useless. Also, shutter glasses give me a really mean headache after a few minutes of usage.

Polarised glasses will obviously not work, since PC screens don'T emit polarised light and can't be modified to do so in a way that would allow the 3D glasses to work.

Coloured glasses. Though these are most likely to work, they would require colour-adapted rendering (obviously) which will make coloured pictures look weird.

Prism screens with vertical interlacing would work and look good, but is not suitable for home use.

Penumbra in true 3D would be awesome though

Would you tell us about the cool things you'll implement, Thomas? Pleeeeeeease
