Polar Express

Another simple Polar Coordinate Blip. The recent improvements to the various blending and healing modes in Photoshop are pretty awesome. Here the cut is at about 2 o'clock but I did it and can't tell exactly where it was. 

To make little planets and tunnels you need a 4x2 photo that will roughly match at each end (a square crop duplicated with one side reversed works perfectly). Then resize to a square and apply the Polar Coordinate filter. For planets turn the square upside down before the filter.
