Yes, now that you mention it, it probably was perspex.

I passed the joint again yesterday and they maintain that they use the "finest optical quality crystal" and not perspex. But lacking data on what type of crystal they employ and a working definition of what a crystal is, I suppose it may still be perspex.

They've been selling those for years in charity shops, images of the Eiffel tower and suchlike. I think it's just done with a laser shone into a perspex block to selectively "disrupt" regions forming the outline.

If they could come up with a robust high resolution colour version that would be quite something.

I saw something interesting the other weekend. 3D engravings made inside some kind of crystal. You sit in front of a kind of a machine that scans and engraves a 3D image inside otherwise clear crystal. The resolution of the image looked a little rough, but it looked like it had potential as a bit of fun, if not exactly a replacement for a 2D photograph.

Ah, you have to be standing in exactly the right spot then.

Yeah - Its like those funny slanty smears on Football Pitches....When you see them on Telly they look like they are standing up in the middle of the grass and you (maybe not YOU but some simple minded people) wonder why the players don't trip over them

They need to get a proper job.

Humbug...

Yes, it's the same for those adverts painted on rugby fields, they only look right from the camera angle.

The 3D effect ones are called Anamorphic Illusions apparently, I found this site a few years back: http://users.skynet.be/J.Beever/pave.htm

It also shows how the illusion is achieved on a couple:

This = This, for example.

That's pretty incredible.

Sure there was another artist who did similar a few years ago but I might have dreamt that...

After all that monumental effort, the sky is grey and it looks like rain

The artwork looks impressive in the photographs and it would be interesting to see how realistic the illusion appears in real life.
