Puts a little twist to visual experience, don't you think?

This one I think is even better!

Well that certainly is different.

I wonder if they have the extra-large airliner size?

I guess projectors and curved white walls is the way to go then if you want something that large.

Given your interest shown in this thread, you'll almost centainly be interested in Paul Bourke's website http://local.wasp.uwa.edu.au/~pbourke/

Yep, definitely read Paul Bourke's papers. He'll tell you how to DIY with a security mirror. I'd like to see someone follow through with a project like that and document it.

Aaarch, LOL. I read everything and bought a spherical mirror like you see in shops for security purposes. Set me back EUR 100,-. I saw huge distortion (wobbly lines and non linear reflection). It turned out you cannot use acrylic mirrors but very expensive and fragile glass or metal ones with the reflective coating on the outside. Apart from that, the image needs to be post processed. If you throw a square image in the mirror, the corners are extremely stretched on the projection screen. So you need to compress the square image to some sort of a half circle. Even if you project into a dome.

I don't have good memories from my dome projection experiments and to make it worse, my projector died last week. Maybe better :-D I'm going for 32" screens.

I didn't know you can bend LCD screens? With OLED you can and I expect a huge leap in dome imaging when these become common. Today the European Union announced that they are going to ban TV's that use over 100 watts. All big plasma's can't be sold anymore from 2012. This will accellerate the OLED technology.

See how the University of Tsukaba Japan has designed a virtual reality treadmill. It helps physical therapy patients learn to walk again. The treadmill is using a 270 degree dome and uses three projectors. Notice the mirrors they are using. Great idea to try.

It reminds me of a Borg regeneration unit. :D

Curved projection is the future of simulation. You will be assimilated into the collective. Resistance is futile. ;)

I seriously doubt they need any of that to walk again, but it's cool technology none the less.

And a cool technique to raise funds for a hobby project ;-)

I've asked for a quote for the mirror Paul used in his project. They are 600 aud. not cheap.
