Percolator
I'm excited to finally get a chance to update the Percolator icon with a few tweaks. Apple recently began requiring iOS icons to be 1024px but the original Percolator icon was only 512px.
The original icon used a bad voronoi texture for the little bubbles, so I replaced that with a more bubble-like texture and rerendered the base C4D scene at 2500px (so I won't have to update it again any time soon.) Post work done in Photoshop.
