Rig Diagrams a la guitargeek.com... How Can I do It?

[denver.p]

I'm just looking to make diagrams of my rig, or ones I'd like to have, like the ones guitargeek.com
Like this:

but with my gear in it.

Any programs or websites?

There was a thread on this a couple of months ago, so search it for more detail. But the outcome is that the GuitarGeeks guys make their own images and jealously guard them.
