Ultra short throw 100" image from 26" and no lens.
200) Lumen at 3500:1 Contrast.
Uses curved mirrors in instaed of lenses.
Looks pretty cool, rather than having a big box at the viewing/seting location you could have a medium sized box on or built into a table at the wall below the projected image.

It's about an order of magnitude more costly than DIY pjs.

I froogled them and they seemed to range between $3500 and $5999. So a little more than 5 times rather than a order of magnitude. But I thought the now lens, short throw was an interesting innovation, placing the PJ at the foot of the wall or on the ceiling. Quite a few people are looking at long throw options to have the PJ fit the room but always having it at the screen sounds easier and more flexiable. I'm not suggesting that anyone buy one just to see an new technology option, I'm not sure if anything like this could be practiable for a DIY.

Personally I think it sounds pretty cool. I'd get one. If had that kind of money to blow on a frivalous thing like a $6000 projector, that is...

Just a thought about this pic:

Anyone else find it odd that the throw distance is in metric but the screen size is in American Standard?

Here is a distance vs image size, same metric vs US, but mm vs inch, but you can see that the image grows pretty quickly with small changes in distance from screen so I can only assume that they wanted to use a smaller unit but americans only understand inches for screen size. Why can the US go metric????

2.5" to screen gives 40" image
26" to screem gives 100" image
