I would love to see a wider angle just to understand exactly how they made that happen.
Edit to add:
How expensive is that stuff? This could blow lava lamps away.

I won't try it because I'd probably wipe my nose in the middle of doing it and end up with a steak knife in my septum.

(47,675 posts)8. I bought a couple of Genesis Physics Corporation speakers in 1983 - ferrofluid tweeters.
The cabinets are huge. The tweeters were about 2" diameter and the woofer was about 12". No cross-over circuitry. Damn were they nice. I finally blew out the woofers (guess why) but by then the "lifetime warranty" was useless since the company no longer existed. Mostly, the ring around the outside deteriorated. The tweeters are still fine. I can't decide whether to get new woofers (after-market) or sell the case and tweeters. I've got a nice pair of wall-mounted speakers that are damn close to as loud. For now, they're in the basement "museum".
