test with two lines moving in opposite directions.
coloured version of the test with two lines moving in opposite directions aka "Homage to George Bush".
four lines approaching from four different directions - a little later.
Tests for creating collision avoidant pathways on a screen score. Rodinia will be the second in my series of "Tectonic" pieces (after Tectonic Valaabra ). The scores will (eventually) scroll across the screen and interfere with one another when they collide (the analogy to tectonic plates), causing disruption to the pitch, duration, velocity and density of one another.
