Show HN: VHS Playback Physics Simulator

I want to study my centroid methodology more conveniently and later prove formally that what I came up with actually results in aligned VCRs. So I have been working on a physics model of the VHS playback - specifically the impact of mechanical aspects of playback on the RF envelope read by video heads. » The VHS playback simulator can be accessed here « I’m not that good at HTML, so it’s just kludged together for the most part… but I think I fixed the most embarrassing HTML-related bugs by now.
