We needed to create backgrounds for our animation that would fit with our style. we decided on this triangular effect as it would go with our polygonal style. I created a normal gradient image like this
Then i imported it onto a web based program called http://somestuff.ru/I
With this program i was then able to set up the triangulation using a set of points and the outcome looked like this.
Dorota then edited the dark one to fit more into our animation and added some moving stars for added depth.
