Hello team,   we are looking for motivated people to create playgrounds that will be used as feature demos:   If you want to contribute here are the rules: - Code should be dead simple - Only one feature showcased at a time - If it can be pretty that's a big plus   Please just provide a playground and if it is ok I will integrate them directly on www.babylonjs.com (Please credit yourself in comments in your code)   Please note that you can also improve existing ones
