Slightly OT
Yes, I am crazy, but I am working with a director who wants to put on a Halloween show this October, and he has asked me if we could do something similar to this.
And with no budget – ambitious isn’t he?.
Anyway, the building is considerably smaller, and we will only be using a single projector in a building about 150 ft from the target. The plan is to get local artists to draw ghosts, bats, witches on brooms, and other Halloweeny stuff. I will animate the objects in Vegas and make a mask to keep the bleed to a minimum.
Has anyone done anything like this and do you have any suggestions?

I haven’t done anything like this before,but it’s really something.
This one is really cool too.

That’s sort of what we are doing. But a Halloween themed show. Mostly for the kids.

Stephen,
What you are looking for here is projection-mapping. You can do it manually – especially if you have a single projector, but if you want to create masks and simulate multiple surfaces you should really be looking at a projection-mapping application that allows you create masks, surfaces etc. By having multiple surfaces you can have different sources playing onto each surface. The surfaces can all be displaying on the same area – but you could for example, have your background on surface 1, then have an animation on surface 2 etc..
If you have apple – madmapper or GrandVj are two applications that spring to mind – GrandVJ also support windows.
Manually will be very, very time-consuming… I tried it and gave up – have been playing with GrandVJ for a while now – V2 has it built in.
Just one point to note – at 150ft – even indoors you will need a decent projector. For example (and I know it is a totally different situation) – the ‘India gate’ projection referenced in Abhi’s post used 4 x 22000 (yes 22K) lumens barco projectors..
At 150′, any standard lens will create an image so large it will be almost invisible even in very low-light. You will need a projector with a long-throw lens, and at 150′ it will need to be bright – I don’t believe many of the conventional consumer projectors would work satisfactorily from that distance.
For example, a Panasonic PT-DW6300US at 150′ throw will create an image of approx 25′ diagonal. That device pushes out around 6000 lumens, and costs around €5000… I would certainly recommend renting something decent.
There maybe more informed people on the forum here – I am only a hobbyist, but these are my experiences…

we are going to meet with the local cable (Community Access) TV station to see what projector they have. As far as software goes, our budget is zero, so a $400 software package is out of the question.
We’re likely going to need to pass the hat among our sponsors to rent a decent Barco projector.
I will probably make a scale model of the building out of foamcore and use a small consumer projector to show our sponsors what we want to do.
