Hi Stefan,

Cool idea for a digital "watermark".

1 - Where do you find the mp3 file inside the 3dm file?

2 - I'm curious how you modeled a knife edge into the 3 blending ovals? Tried to reproduce that and I get close but with a slight bubble on the Y-axis center seam surface. Tried sweeps, blend and network using the curves in your 3dm file.

Thx.
