This is an implementation of the Rotation Waveguide using the code module in drambo, allowing for a full pitch range.
I included a dispersion knob and a drive knob. Be careful with the drive, it can blow your ear drums (or your brain if used wisely :)) the patch shows how you can make use of it by connecting it to a sustained envelope, which allows you to play the resonance. You can create all kinds of sounds though by modulating the parameters. It also pairs well with the FDN module or a second rotation waveguide to create additional resonances.
It crashed drambo on me sometimes, not sure why, but this is is the most stable version that I could come up with.

Kudos to chair audio!
