In the current political climate, that bit makes a lot of sense.

Again the lesson is never hire a woman. Just not worth the risk.


Of course I'm joking! I love women. Some of my best friends are women!

It's not gyroscopic so much as reaction wheeling - it uses solid state gyros to detect movement, but then opposes any toppling by the torque reaction of spinning up a flywheel rotating in the same direction as the incipient topple. It's the same principle that tightrope walkers use - though they have a long heavy pole instead of the reaction flywheel.

"incipient topple"

I going to use that in the future. Maybe even in context.

I don't care who your are, that's cool.

Cubli. Perfect present to put under the tree for the little ones.

I call bullshit. How is the green light getting through the solid yellow pencil?

But you're ok with the red and blue light getting through? What about the magenta?

Maybe it's just a really reeeeeally polarized filter. :P

I'm just prejudiced against green.

I suppose the filter *could* just be stretching out the images along the whole length of the filter - in which case it would be useless for viewing anything that's not straight and regular along its length. That would explain the 'trick' without needing photoshop-style trickery.

I'm not saying that is how it was done - it's just one possibility.

Clearly gnome is a green racist but I too have problems with the color blue.

ceptimus is, as usual, right: the plastic thingy diffuses light, but only in one direction. As the pencils are linear objects, we don't notice the smeared out image.

Now for something classic:

That one really has been faked. The whole point of that illusion is that white squares in the shadow are as dark as the dark squares outside the shadow. If you physically move a dark square into shadow it becomes darker still.

I wonder what it looks like from a different angle or under different lighting conditions.

There are definitely some weird optical illusions.
