Mike and I now have a DLP projector, which is like having a six-foot television in our living room. Right now it is used for Halo 2.

What does DLP stand for?

I think it's "Digital light processing" or something like that. It's a MEMS technology which uses an array of (millions of) miniature mirrors on a chip that can be tilted to different angles in order to reflect different amounts of light. A color wheel sends red, blue, green, and white light alternatingly to bounce off the chip and onto the surface. It's generally better than LCD because it doesn't require three different imaging devices per pixel (so there is greater pixel density for cheaper), and the colors all end up exactly on top of one another, and the pixels can be larger. Anyway, it looks sweet.

The nanobots are lulling you into a false sense of security. Watch out for the red-green-blue-gray-goo!

Yeah, I think "cheaper" is a more effective term than "better" here. Though we can all agree it's good to be able to buy a projector for under $1K. Sometimes the RGB alternation is visible, for example when your eyes move quickly to track an object or to jump to a new line (e.g. watching subtitles), and thanks to POV for an instant you see the three layers of light separated out. It can be a tad annoying. But like I say, not too bad a price to pay for a six-foot TV under a grand. Do you have one of those cool screens with the glass beads? It's a lot brighter than projecting onto a wall.

Well, I think even the higher-end projectors are DLP, just with faster color wheels (and more "white" channels) so that the rainbow effect is lessened or gone.

We're just projecting onto a wall.. I'm not that rich. ;)
