All musicians hope that when they play an instrument, there will be a reaction; this program seems to do just that. We’ve seen projects where movement created sound, but this time sound creates movement. PD GEM seems to have been programmed to play certain shapes and patterns of movement depending on the pitch and pattern of the keys struck on a piano. Depending on how sensitive the program is, it can make the performer responsible for not one, but two completely unique demonstrations at once. The only part that kind of boils my broccoli is how simple the shapes in the beginning are. I know it leads up to a more grand and visually interesting conclusion, but the last thing I want to see in a piece such as this are the stupid triangles and circles that even I can create. However, that’s just me…
