I recently saw a new device that has some interesting applications for projectors. It is called the Geo Tahoe. I don't believe there are any devices out there using it right now, but hopefully there will be soon. It looks like it could correct for pixel misalignment and chromatic aberration. Another cool feature is the ability to shape the image for those needing keystone or wanting a curved screen. A Torus may now be possible with a digital. Peter are you listening.

Driven by the powerful Geo processor, the Tahoe evaluation board provides advanced
geometry processing features, such as correction for lens distortion and lateral
chromatic aberration, geometry distortion, and rotational misalignment. With up to 16-bit
internal processing for each channel, Geo can achieve color convergence at 1/32 pixel
calculation accuracy and rotational correction with a resolution of better than 0.1o. Geo
also supports up to +/- 70o Horizontal keystone correction, +/- 70o Vertical keystone
correction, and +/- 10o Tilt correction.
