I'm with you there, GryMor. Baen's Webscriptions service is awesome. I've bought dozens of E-books from them in the past year. Zero DRM, and I don't need to worry about misplacing books:). The books are also a few bucks cheaper than print. Now they just need to get some more publishers to buy in to the concept.
Roland Piquepaille writes "According to Technology Review, researchers at Hokkaido University have developed a new way to create the feel of flowing water in two 3-D virtual-reality simulations, one for fishing and another for kayaking. Mimicking fluids is a difficult task using the complex Navier-Stokes equations. And these equations need to be running constantly to keep pace with the ever-changing movement of water. As this involves lots of computational power, real-time simulations have been limited to 2-D up to now. So, these new 3-D real-time simulations are using special tricks by doing some calculations in advance of the simulation. But read more for additional references about this research on haptics."
