This animation appears to be the work of graphic designer Morgan Harary aka Bloodsugar. The attribution (and earliest discoverable appearance of the artwork on the internet) comes from this blog post at HOUSE OF ♥ THROB. An archived copy of Harary’s now-defunct website identifies that blog as Harary’s. This 2009 article says that Harary works with loops, logos “and a nearly unlimited range of effects” to create “club visuals” for Boston-area dance parties “like Hearthrob and … Thunderdome.”
