It should give seaweeds generally and possibly doublons at high speeds. Here are animated gif movies with different growth velocities.
Times are approximate.
This is the degenerate or 45 degree growth. Molecular weights are 136 and 80 respectively. This is the sample drifting with respect to the camera and not a tilt in growth direction. I will take more reliable data if this is something we pursue further, but the general form of the growth still comes across. To the left of the tip, there is growth that appears somewhat weedy.
