A friend just forwarded me a rather cool use of Halo 3's Forge editing environment - a self-portrait! Keep looking at it if you don't see it at first - it sometimes helps if click on the image and look at it in a larger form.

Some comments from the author's post:

I wanted to approach this with a completely different technique. I was thinking that an image could be created if objects were placed in the foreground, middle ground and background and then viewed from a specific area that would converge the objects to make the image. If done correctly, the image would appear vertical and 3D as opposed to lying on the ground.

I decided to try this by doing a self portrait. The face would be made using facial shadows. The forge objects (vehicles, boxes, weapons, etc) would create those shadows. The sand environment would be the negative space between (the flesh of the face). It ended up working out pretty well. The tough thing was positioning the objects so that the face maintained the correct proportions. For example, the mouth is about 100 yards away from the eyes, but it looks proportionately correct. Once I had all the objects placed (which took a while) and had my viewing location marked, the objects converged together and made the image. The cool thing is that the image begins to break apart once the player starts moving in any direction. Also, the foreground, middle and background perspective technique makes it to where I could distort the image itself based on how I move. For fun, I viewed the face from a gravity lift and watched the face scrutch up and stretch out.
