Or you could make your own overlay. I went to a local photocopying / printing place that did promo posters and printed architectural plans. These guys have what's called a plotter / printer and it prints onto sticky back vinyl. They can take any picture / pdf / etc. file and print it onto the sticky vinyl. They can also, for slightly more money, tell the plotter to cut out certain areas, very accurately.

So you could get a faceplate scan of the VCI-100, put any design / color on it - and the controller labels, have it printed and cut, then just stick it on the faceplate. It's waterproof, fade proof and totally removable, in case you get bored with the design in another 12 months. Attached is one I did for a controller I'm trying to get working at the moment. Turned out great, total cost €8.00.

Cheers,
