Butterfly
Channel fluid from a round pump line into a flat ribbon — flush beneath your silicone prosthetic, with no tell on camera.

The problem
Round tube. Flat appliance.
Pumps push blood through round tubing — but a round tube telegraphs through silicone as a visible ridge. Artists have rigged around this by hand for years.
The invention
Round flows into flat
Inside the Butterfly, the bore morphs from circular to a wide, low ribbon — preserving flow while collapsing the profile to almost nothing. Push-fit inlet, no clamps.
