Weird is a PT2399 delay where your input signal controls the time parameter.
This idea was totally random. I originally was experimenting on a the Bit Pirate breadboard with heating up the input signal to control CMOS chips and realized I could probably use this to control the PT2399 chip. And so I tried this out one day and it turned out to be one of the weirdest effects I have ever heard. Simple but potentially genius!
