Alan Thomas: Magic Mirror -- music for guitar, harp and computer inspired by M.C. Escher 

"Magic Mirror" is from the album "Elusive Symmetry" by Eleanor Turner (harp) and Alan Thomas (guitar). The piece is an absolutely strict mirror canon, in which every note played by the guitarist is reflected in strict intervallic inversion by the harpist about 2/3 of a second later. The computer (in the form of a MAX/MSP patch) processes the harp and guitar sounds in real-time to add a third layer to the "trio".
