I don't know if anyone else has played revelation, the fourth installment of the myst series, but it contains a very obvious WILD reference. Not to give away too many spoilers, but at one point you travel to an alternate universe called "dream". You enter dream by laying on a stone bed and staring at a stone mask above you. A light show follows and then a cutscene with peter gabriels curtains. The rest could spoil the plot but I just thought I would post because i'm almost certain this is a reference to WILD.
