My friend and I are working on a web based game where we want to have a blackhole-like thing rendered in some form of an engine or 3D program for us to freely manipulate adding more "arms" making it smaller or bigger and playing around with its light.
Here's a picture of our concept of the graphic element:
We want help to find the best possible solution for this, and possible also some kind on guide to create these elements. So far everything is designed in photoshop but if we want the hole to be dynamic we can't use pictures.
