All code and graphics by me (@kriblo). Music is the first minute of Be Svendsen's Bones in a loop. The circle face kriblo image is from another one of my projects. I made the rings by turning the original vector graphics into bitmap, made 10 duplicates and then copied precisely sized (black) filled and non-filled vector circles onto the bitmap costumes. Then I used the bucket tool with "transparent color" to erase all the black. It uses ten ring clones which moves around and rotates, and one non-clone which controls the clones, and fades in when the clones are in their original positions.
