I did not look at the source code yet, but is this some sorta physics modeling problem? Treat the strings as a a bunch of interconnected balls, then apply the force at point, compute other forces, interpolate a curve through the new state, then compute frequencies based on where the string was plucked? this is pretty cool

My guess is the strings are not modeled as balls balls as continuous lines with a set tension oscillating based on their length and thickness. It's presumably a bunch of trigonometry, but not the most insane modeling problem I've seen. Very cool none the less

What's the most insane one ?
