GPUs are making this the era of high powered desktop computing and to prove the point what about a nice example of fluid simulation - video and code included.
The idea is to get close to the physics by solving the Navier-Stokes equation so the smoke you see swirling around the cylinder isn't just a special effect but a simulation of the fluid flow. Watch the video to see how it performs. It is worth mentioning that the video is a representation of the simulation in realtime - that is it is what you see when you run the program.
A project to make spider robots come alive via your smartphone has already reached its initial target on Kickstarter. A bots_alive kit transforms the remote-controlled Hexbug Spider into an autonomous [ ... ]
