- Er, heh, well, due to cost limitations, we couldn't
- afford to do that :-) We _did_ try using beam splitters
- and multiple LCD panels, but we still lacked brightness,
- and we were still running a small number of vertical
- pixels (8? 16? I can't remember). But ya gotta remember,
- if you have to get a lot of lasers, then they have to
- be calibrated together. They may suffer from aging at
- different rates (if that's possible-I don't honestly
- know). In any case, they'll cost a lot more, if you have, say
- 16 lasers for each color! But you are right, that
- would help a lot, especially if you beam split those
- lasers into like 256 or more beams...

- Anyone want to give me the next 6 lottery numbers so I can
- win $5M to try this out? :-)
