+.SH SYNOPSIS
+[-xy]
+.B blind-mosaic-corners

+.TP
+.B -y
+At the upper and lower edges of the video,
+wrap around to the opposite edges.
+.SH REQUIREMENTS
+.B blind-mosaic-corners
+requires enough free memory to load one full frame into
+memory and 1 bit per pixel on a frame. A frame requires
+32 bytes per pixel it contains.
+.B blind-mosaic-corners
+is optimised for simplicity rather the memory usage.
+.SH NOTES
