Moiré Kit

This pack comprises an in depth investigation into the fascinating properties of Moirés, or interference patterns.

There are 7 sets of screens (18 x 12.5 cm, printed on photographic film, although one set of screens is double size) each demonstrating a different effect. One of the most amazing effects is where the Moiré pattern becomes magnified, when you rotate one screen against the other.

Another amazing effect is when you slide the top screen sideways, and part of the image moves left, and other parts move in the opposite direction!

I found this channel by accident while Googling something else, and I just spent an hour and a half watching this guy play with toys.

It is an LP-1218 Light Panel. I think they are still available, although we bought it a few years ago, and there are probably newer models around.

i actually respect this man. he is a very bright old chap isnt he :)

[grandillusions]

He has been collecting toys for nearly 30 years, and he has travelled all around the world, visiting toy fairs and also other toy and puzzle enthusiasts.

[grandillusions]

Mostly the toys are from Tim's collection, and are not for sale. This is one of the small number that we do sell.

This guy has so much charisma and such a soothing voice.

[grandillusions]

Tim feels his life is so busy as it is, there is no spare time for anything more. Also he is in the Grand Illusions office at least once a week, so if there is a link or website he wants to see, he uses one of the computers in the office to view it. And people know they can e-mail Tim via Grand Illusions.

Way cool.
They remind me of demo effects, like on the C64 and Amiga.

Tim is like the grandpa you just can't wait to visit

I'd love to see more of this kit.

2:00 You can see how it works just looking at the video. One sheet has small slits. The other has compressed hearts and spades. The slits get a little bit of each heart and spade, each one slightly moved relative to a given heart or spade. So they look much wider than they are printed. It's essentially Nyquist aliasing, where your sampling frequency is too low.

[hughcornish]

That is incredible. As always. Tim, you are an inspiration.

HBO's old movie intro that ran for several decades used this phenomenon to produce the starburst shot in the beginning. Layers on layers of acetate rotating and counter-rotating. There's even a documentary of the making of the intro...lol

I've played with moiré screens before, but never any with such amazing effects!

Most interesting and entertaining. Your videos are always amusing and intriging. What a wonderful channel :))

This is my favorite video of Tim's, such a wonderful toy.

The Bright Eyes album "Cassadaga" comes in a CD sleeve with patterns like this with a little decoder window thing so you can read it.  The CD itself wasn't that good, but the package was entrancing.
