Since I forgot to post last wednesday, I will post twice this week :)
A while ago I played around with creating a parallax effect with stars on an HTML5 Canvas. After tiding up the original code I wrote a little bit, I have decided to release it in this website. It will not, however do well as a screensaver due to the high CPU / GPU usage it induces because of the inefficiencies in the code.
It can be found here: parallax scrolling stars
I will (hopefully) write a technical post in the near future that will explain how it works, including an explanation behind the high CPU / GPU usage.
