An early casualty of the GIF tournament we've been discussing is this one by Scary Attack (GIFs larger than 300KB go to my "wider blog" for shelter -- this one's an ungainly 3.5 MB).
When you open it up in a GIF program you see it's 99 frames, about a third of which are blank or transparent. The frame rate is set to zero, which means in a GIF program it moves with a stroboscopic flicker. In a browser it moves at one-tenth to one-twentieth of a second, so the eye can see what's going on. And it appears rather simple: a Mondrian-style grid of blue, black, white and pink.
There are a zillion or so Mondrian-style grids on the web but my feeling is you can't have enough of them. It's an enduring form the way certain arpeggiated chords always sound good. Scary Attack makes his erratic and glitchy, kind of the opposite of the obdurate universalism of de Stijl's horizontals and verticals, more like a badly wired neon sign. The pink is something Mondrian would have self-immolated before using. The piece also has a bit of an Ad Reinhardt flavor (except for that pink): very faint sub-grids of smaller rectangles (blue on black, blue on blue) can be seen, much as Reinhardt played with low contrast adjacent values. The main appeal is something Reinhardt couldn't or wouldn't do: the constant cartoon-like intrusions of one rectangle's space into another's. This happens in an unpredictable way, with enough variation over 99 frames to keep the work engaging. Sometimes the little pink rectangles get "stepped on," which is humorously pathetic.
