GIMP at Libre Graphics Meeting 2024 (Rennes, France)

[Tas_mania]

Thanks Krikor.
Most of it is French  I used spline spirograph by David Tschumperlé (in later versions of G'MIC.) I found a technique to use a spreadsheet to set animation parameters like angles and from there into a batch file. It goes from -360 to +360 degrees at 4 degree increments
