"Windowpane" is a song by British experimental band Coil, from their third studio album, Love's Secret Domain.

Written and produced by the band with lyrics by John Balance, it was released in 1990 by Threshold House on 12" vinyl and CD; in the US, the single was licensed by the indie record label Wax Trax!

Regarded as a “proto-‘trip-hop’” track, the song refers in the title to LSD encapsulated in thin gelatin squares, with the lyrics referring to the subjective effects of an LSD trip ("See microscopic, see world view, see the future leaking through; see the person who once was you").

The second one was released on the label Wax Trax!, with catalogue number WAXCDS 9142.
