Music like Polygon Window

Surfing on Sine Waves is a studio album by Polygon Window, a pseudonym for the English electronic music producer Richard D. James, better known by the alias Aphex Twin. It was originally released on 11 January 1993 by Warp. It is the second release in Warp's Artificial Intelligence series. The 2001 reissue edition includes the previously unreleased tracks "Portreath Harbour" and "Redruth School".

The cover of the album features a photograph of Chapel Porth beach in Cornwall, where James spent time with his sisters as a child; James thanks the seaside village in the liner notes. The title Surfing on Sine Waves was chosen by Warp founder Rob Mitchell after James mentioned that "loads of people I knew growing up in Cornwall were poser surfers and I didn't wanna hang around with them."
