This project uses the concept from Splou's project, which you should go check out, but it tailors it to movement speed. I think the most realistic of the settings is 4 Blur and 30 Blur Length. I'll try to make my next project a remix of another with this motion blur mechanic.
WASD. Or, to be more specific, AD. Play around with the Blur and Blur Length settings and get some funny effects!
