Radial Name Wheel

Sixty labels laid around a circle eleven hundred pixels across, most of it off-frame, so you only ever see the arc that passes through the viewport. Scroll rotates the whole ring by a ten-thousandth of a pixel per unit, which is why a very long page turns it slowly and evenly, and every label is re-placed with cos and sin plus a rotation matching its own angle so the type stays tangent to the circle. Hovering a label pushes an image into a frame that trails the cursor, clip-wiped up from the bottom; leaving wipes it away from the top, and older images in the stack clear on a delay so a fast sweep leaves a brief trail rather than snapping.
