Well I thought it was cool.

I've tried my hand at projection mapping a couple times, not at this level of quality - kind of a fashion thing here. Google Battle of Branchage if you want to see another big project of the same kind.
Now how would this be applicable to landscaping? Perhaps you'd like to project a garden gnome in your neighbor's neo-functionalist yard?

Here is a link that might be useful: New Year 2011

I can just imagine built up, urban downtown shopping sectors transforming into cool, verdant forests at nighttime. Speaker systems can imitate the sound of wind rustling through the leaves and the calls of unseen wildlife. If you are unable to create a park distinguished geographically in a city, creating a purely temporal experience of a forest may be your best alternative.

I liked it!
I wonder where this will go?
Lotsa possibilities on what this can be projected on.

More stuff can be found at vjforums.com at the Inspiration thread (Gardenweb wont let me post the link). I found something similar to what Audric described, but it was shameless commerce by Samsung, and somebody did just the opposite and projected a helicopter on the cliffs of Dover.
We (me and DH) were asked to project on a forest, as part of a performance, they asked if we could make the forest move... we had to say it was beyond our means both technologically and financially.
