Airdrag was involved or not? The shape is also oscillating between convex and concave triangle. I also think the diamagnetic and gravitational forces can cause crazy things. Remember that water is a very weak plasma and the very strong magnetic field can cause electromagnetic effects in the water.
I doesn't look like a well known physical condition to me. If you play the game I-Fluid you often notice a triangular shape of the drop when it is moving over matter. I don't know if it is a physical effect or a design decision. Games are a mixture but the physics simulation in them are often very impressive and continually getting better and what we need are pictures and not figures (numbers) so I think physics learning can come from games..
