Great engineering roland. I like I like.
I have never used a stepper motor except by manually mucking about with wires and power. Ive got a beauty in the shed though - Im not sure what Id use it for!!!
I have scoped lazy susans as potential bearing systems. I was intending a while back to make a tracking system for directing sunlight in thru the windows of the house for heating porpoises;). It would have been a two motor jobby - one axis much as your lazy susan, and another tilt axis.
I did some experiments by manually placing a bunch of old mirrors against the front fence to direct sunlight into the front dining room. Im not sure what extra warmth the mirrors actually provided, but do you know what happened? I BROKE THE FRONT WINDOW!!!!!! Big crack strait across 1m*2m glass pane!!! Cold glass obviously does not appreciate local hot spots !!!! BLOODY MURPHY - another mad project comes tumbling down. In my case, I think the 'D' in R+D stands for disaster!!!
Further on 360 photo systems, the Australian Navy has a web site that allows photo tours of vessels. Some shots have been made using a 360 lense allowing the online user to scroll around the room at will -obviously some on the fly processing to flatten out an image section is used. I like this method, but it must have drawbacks or you would see it employed more often?
Regarding image stretching, I have an idea of putting a person inside a white hemishpere and using several projector tv's to beam onto the screen from the outside - so the user is immersed. I cannot see any problem with creating a simple mockup prototype for this idea.
Another idea concommitant, is to put the user within their personal projection dome upon a 2D treadmill ie. A treadmill that moves in X and Y plane. If you imagine a large enough sphere, you stand on top and bobs your aunty - spin the ball = XY treadmill. Let the air out of the ball - stretch it flat over a powered omni-roller framework. Power and control can be provided wirelessly to the motors and controllers within the XY treadmill.
Not the simplest mechanism but feasible none the less. Obviously the r+d would involve Risk of Disaster or worse Disgrace, but wots new!!!!
I have previously made a RC omniwheel robot base with custom made omni-wheels, and using those wheels it is simple enough to create a ball bot. In NUTS and VOLTS site I saw omniwheels used for this exact purpose. I have not seen many ball bots though there are a few around.
I have photos of RC Tank Esky and Omniwheel base, that I should post at some stage.
Truth is that Im dead sick and tired of my Kodak Quicktime software that does maddening things when I try to upload stuff to sites like YouTube!!!!!!
Can anyone suggest a popular brand of camera that has tried and tested software --- Im sick of Kodak!!!

Hey Davey :)
If you are looking for a new camera, check out the Panasonic Lumix line - They are small but have really great lenses and shoot great video as well (on of my mates just bought one and I was really impressed).
I'm pretty sure the 360 deg view you were talking about was made using Apple's Quicktime VR.
I have seen a couple of those and they are pretty cool (actually one of the ones I saw was a VR recreation of David Hick's cell in Guantanamo Bay which was pretty weird - and cramped).
Also you might be interested in this video of an endless treadmill that I saw a bit ago... I saw another one that was based on a sphere but this looks like a much better implementation.
I vote to not be on it when the software crashes! :)

Cool project Roland!
The finish looks a lot more professional than the pile of electrified spaghetti that I usually end up with! :)

Thanks for the links Ash,
It always seems its been done already. I wonder how their treadmill mechanism works??!!!
I wrote a two really crappy sci-fi short stories. one of them is about a large 3d treadmill used as a prison, and the other is about a web cam enabled dog used to attack a hated adversary. interested??? There is no time to make these crazy things so I thought Id have a go at a kwik word sketch --- ??? should I post these when I get over my lazy fatique? --- its not strictly robix - but related.

Yeah definitely, post away! I'll add another section to the forum or knowledge-base (which is structured like a book anyway) for that sort of stuff.
I also have a couple of short stories (not finished at all) with (suprise, suprise :) robot related themes in them so i'll post em as well.
As far as I know the treadmill works because it is a loop made up of strips running perpendicular to the main loop (if that makes sense). When you walk forwards and back it scrolls the main loop and when you walk side to side it scrolls the mini strips that make up the band of the loop.
Pretty impressive stuff when in action. Where the hell is VR these days?? We have the technology, let's get some matrix action going! :)
