Within the game assets are a few variants of this image, depicting a distorted face with a psychadelic filter. The file name makes it clear that this is a reference to Aphex Twin, but the image itself is a direct reference to the song "ΔMi−1 = −αΣn=1NDi[n] [Σj∈C[i]Fji[n − 1] +Fexti[n−1]]", as featured on the EP Windowlicker. Viewing the song through a spectrograph, a device or program which provides a visual representation of the audio's frequencies, this face will be revealed. The waveform included, similarly, is where the image in question appears.
