Dear ml5 community,

Fixing a Bug? Adding an Update? Submitting a New Feature? Does it introduce a breaking change?

Hey,

I added the link to the new example i contributed, which was merged later today ( #1147 ) If you could put the example on the p5-web editor and add the link, that would be great. I've already made a webeditor version of this: https://editor.p5js.org/tlsaeger/sketches/_QCppDOa8 but I think it would be better if this lives in your ml5 account.

Thanks Tom

Thanks @tlsaeger! I'm actually going to see if I can get a script in place to update our examples now so that we can get this going!
