Eurion constellation

Okay, this is fascinating. You know how modern photocopiers won't make copies of some currency? /. has had some recent stories about currency detection in various products, here and here.

What's most fascinating is how they do it. In this comment on the second thread there's a link to a PDF which shows the pattern that the assorted devices and software are looking for (in the blue channel, apparently). Incorporate that into your graphic design, and "poof", you put your users through issues while trying to scan or reproduce your artwork.

I need to figure out the exact ratios involved so that I can make a T-shirt...

So can anyone point me to an image that can't be opened? We had no problem opening a screen capture of that PDF, but I don't have Photoshop on my computer at work, and i hate to keep pestering people who do to try stuff.
