When I uploaded my sound waves script, which implemented sound waves into Powder Toy, people really liked it. It didn't actually make a noise, but it was an energy with weight, so it caused ripples in liquids and powders.

This suggestion is mainly to bring these awesome sound waves into official TPT. Since there was no update function, it would be really easy to convert my code into C or C++. I think, anyway. It's been many months since I last looked at it.

I will link you to the thread where I uploaded the script, but I have to warn you that I'm on an iPad at the time of typing this, so I couldn't turn it into an actual link manually. Unless the forums does that automatically for me. But enough stalling, here's the link: https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=20553
