A 3D Social Net Working Site (http://bit.ly/9yGMrO) was launched for publishing 3D Simulations. It is to 3D Simulations like what youtube is for videos. The teachers / Professors of Science , Engineering, FEA, CFD can download the 3D simulations from here and embedded into PowerPoint slides and show interactive 3D simulations to the students, making the teaching of Science and Engineering very interesting. http://bit.ly/9yGMrO
