Click the screen to set the Effect Layer (using some sample effects taken from the AnimFX library). Press the space key to load a project (group of pre-configured blobs). Press any other key to view some individual curves.
Note - there is no direct interface for configuring the blobs in this version, but if you download the source, have a look at the configuration list dumped in the message window. Use that with the specified callback methods to experiment with mulitple blobs, effects, overlays and curves.
