My 3D glasses are a free set I got as part of an advertising feature at the cinema. They are cardboard, but the gels in them are pretty good. They are getting a bit fragile now, but I know what the colours should look like when it comes to replace them.

Another route to go if setting up a monitor is too much (I think most LCD screens are not fast enough for shutter 3D displays, but this will change obviously) is to make stereo cards and use a viewer. Look for a book entitled A Village Lost and Found by Dr Brain May (he of Queen guitar fame - he collects stereoscopic images). The book is full of stereo images from his collection, and comes with a standard card viewer which will work with most you’ll find in antique shops. You can, of course, make your own by printing out images to the correct size and putting them in the viewer.

Mattel also make a 3D viewer for the iPhone (should you have one of those devices) and you should be able to make 3D images for that. It looks a bit like a View Master which your iPhone fits into.

I can’t check the video at the moment - I’m on a slow connection on holiday. I’ll try to remember to look when I get back home to the braodband network. Doctor Who is a life-long obsession for me too. Current series picks up very soon, I understand.
