content: And that is just the sort of thing our stupid local council would see and then commission some 'artist' to create.Then erect it in the local square and tell the rate payer "It only cost $150k".Right, I am off to see the council now...

content: The water was cold and colorless. Some better components would have resulted in both a warmer tone and warmer water. They should have sprung for the magic stones.

content: The content creator says right in his description that the effect is an artifact of the camera framerate combined with the water/sonic frequency. You would not observe these effects with the naked eye.It's similar to stroboscopic video.

content: This is one of the stroboscopic videos I really like. This one does a good job showing the dynamic nature of engine valve spring motion.Here is one of the coolest stroboscopic videos I've ever seen. Things get real interesting around the 2:45 mark if you don't want to hear the explanation beforehand.

It gave some insight into another way of solving a problem that's been festering for years.Electronic music isn't the only thing he does:http://www.nbr.co.nz/nigel-susan-stanfordhttp://harmonicjunction.com/nigel-stanford-interview/
