In the summer months, a breeze can set long grasses waving in an impressive display. Similar behaviors are seen in aquatic plants during tides. Researchers simulate the behavior in two-dimensions using a flowing soap film and nylon filaments. Flow visualization reveals the strong differences between flow above and between the grass. Vortices recirculate between the filaments at speeds much slower than the flow overhead. The instantaneous interaction of the high-speed freestream, the unsteady vortices, and the resistance of the grass results in familiar synchronous waves of grain. (Video credit: R. Singh et al.)
Because the only thing anyone needs to be special is to believe that you can be. I know that sounds like a cat poster but it’s true.

I watched this on the plane ride. Twice.
This is a great breakdown of Edgar Wright’s visual comedic choices, and it’s good advice for screenwriters too.
