Tessellation of roller skates. Currently displaying a repeat in 4 sets of colours. Also available at different scales and with black lines or no lines - and, of course, in any colours or decorative details a roller-skating team might request. The underlying symmetry group, p2, includes diads. So, in a different colouring scheme, the design could be bidirectional. Other colours, stylings, sizes and orientations are available on request and you can even ask for a combination of several designs together.
