Some people use software to visualise sound, watching the pretty patterns on their XBox 360s or PCs. That’s all fine, but after watching a few videos on Youtube about the weird things cornstarch does when vibrated at certain frequencies. At high frequencies interesting patterns appear followed by strange looping fingers. At lower frequencies, but higher volume the whole lot jumps around in a strangely organic way.
This was 60Hz at quite a high volume. I thought it important to check my neighbours weren’t in and to wear ear plugs.
