Magic art powers

As an intertemporal avant-garde painter, my magic art powers allow me not only to travel in time but also to read minds and become invisible. Although this can be useful now and then, it's not really the point.

Recent telepathic experiments have established that the black square is the main conduit for the avant-garde thought virus through the ur-dimension. Unfortunately, we inhabit one of the minor hell-worlds, far from the centre of things. This is why the thought virus is so attenuated when it reaches here and can only infect a few select individuals inhabiting separate spacetime locations (with the notable exception of the early 15th and 20th centuries).
