I think there are potentially on the web some folks who would love to export / use some Shadertoy shaders as screensavers.
As suggested by the team, to test this, I passed some license compatible shadertoys shaders to Vuo :
• IQ - Iterations - shiny : https://www.shadertoy.com/view/MslXz8
• KIK - klk's Simple Plasma : https://www.shadertoy.com/view/XsVSzW
• JoshP - Simplicity : https://www.shadertoy.com/view/lslGWr
My fav is KIK's plasma ;)
PS : The authors and the links and the link to the licenses are inside the shader codes for each file.
