This is a very short animation I made when experimenting with flash some years ago. Not complete.

thats was faster than i could say what...

[@ChrisGozzardThatPhysicsGuy]

What? :)

[@Rand0z]

@ChrisGozzardThatPhysicsGuy I meant this was very quick, you could have explained the material optic fibres use, and why there is a material with a high refractive index on the inside...

[@ChrisGozzardThatPhysicsGuy]

OK.
