[Canvas] creating brilliant results by dynamically generating pixels

In this example, the particles are actually pixels that are dynamically generated by js Code on the canvas! These pixels are regularly moved by a moving method. Through this idea, we can think of a lot of amazing results, but this performance remains to be investigated. Experiments prove that if too many pixels are controlled dynamically, it will be stuck! If you have experience in performance, please give us your valuable comments! Does this idea work?
