You know how in the rappy snappy demo there's that A/D keypress/active visualiser? I think it'd be super cool to make one of those with some keypress actions that would differentiate all possible socd/rappy snappy settings and then display what would happen based on your setting
for example:
Light press on D
Light press on A (not as deep as the initial D)
Another press on D down to like 60% depth
Raise D slightly
Bottom out D
Bottom out A
Release D
Raise A slightly
Press D down slightly
etc
