Video: Colloid
I had lunch with Craig and Ava this afternoon at Curra’s, and one of the topics discussed was Roth IRAs. I found it funny that they’re liquid in the sense that you can invest in whatever stocks you want, but they’re illiquid in the sense that if you try to take money out before you retire the guvmnet takes like 140% of it in taxes or some shit. That reminded me of colloids- they act like liquids when you put something into them slowly, but if you try to take something out quickly they solidify and resist.
Here’s a video I made of cornstarch and water, in a plate on an amp connected to my synthesizer. I added some drops of food coloring to show how the particles flow. The amp was actually playing a single note from the synth; the music is tracked separately.
The songs (“Orange Peel” and “Roundabouts on the Wrong Bus Routes” “Between You and Me the Sky isn’t Blue, it’s Green”) are a couple I’ve had laying around for a while and they seemed to fit the movement of the colloid. I can’t convince other people to play my songs so I play all the instruments.
It’s alive!

yeah, at about the 2:00 mark the large greenish blob seems to become sentient and runs around aimlessly before collapsing back into the vibrating mass.
Very much like life :)

Re: Roths
Don’t forget you can also take out everything you contributed with no penalty. And then some more for certain house-buying/educational/health expenses.
Re: amp-colloids
Wow… it looks like you animated that! I had no idea that would happen. Watch your email for another freaky idea to try.
