Just noticed a bunch of notifications and it appears I've been featured which is pretty cool! I have no idea how a 3 year old project of mine got featured but hey I'm not going to complain! Why not check out my other projects, they're much better than this one! https://scratch.mit.edu/users/RobFarley74/ So this was just one of "those ideas"... Hit the green flag to turn it on. Slider will adjust the number of blobs it's working with, the fewer the faster it'll run. Hit the green flag again for it to kick in. Clicking the Lava Colour or Lava Liquid buttons will change the colours of the lava or liquid.
