As an exception, I will post the sample for now, and come back with the informative and explanatory blog post in a few days, since my exams don’t allow me too much XNA work at once.
So the first sample deals with the XNA implementation of something similar to the mouse cursor encountered in World of Goo. My blog post later this week will contain more information about how I built the sample, but until then, you can try it out, and play with it.
To download it, access the sample’s page, here.
Have fun toying with the configurable parameters! 🙂
