rosemarie fiore's firework drawings are made by exploding and containing live fireworks, "resulting in bursts of saturated color that are overlapped and collaged into abstract compositions." i love how the explosions leave little indexical traces that look quite photographic. take a peek at more of rosemarie's very interesting work here.
