Super Mega Rampage is a complex constellation of polymorphous pop forms such as bubbles, spirals and explosive penumbras of color that conspire with overlays of automotive schematics and a variety of ghostly squiggles. It's all kind of nostalgic in a creepy sort of way, like those old, faded signs and commercial facades on Airline or Jefferson Highway, surfaces with palimpsests of earlier graphics peeling and fading into each other amid layers of more recent graffiti. It also reminds me of what happens if you've been driving for 16 hours, subsisting on junk food and coffee, and then try to go to sleep in a strange motel — this is what you see when you close your eyes. Horrible but compelling, this is what highways would dream if they dreamt.

More subtle and mysterious, Power Up is another 4-by-5-foot nimbus of vaporous clouds, continents and digital artifacts like disembodied smart-bomb guidance graphics cast adrift in cyberspace, a soporific if unsettling vision that somehow reminds me of Vice President Dick Cheney. That sense of high-tech horror lurking in the collective unconscious takes an aggressive turn in videos with titles like BoomFriendly Fire. The interesting thing about Sullivan's latest pieces, besides their unusually taut graphics, is how they actually do seem to suggest ghost broadcasts beamed from long-lost communications satellites all blending into each other in a kind of autonomous electronic unconscious from beyond the ozone layer. Nicely done.
