I am going again this year at Eurographics, a conference that I really appreciate and which will be held from the 11th to 15th April. Certainly, less famous than Siggraph but probably more specialized. It's going to be intense once more and eventually very educative especially because I will also attend the "Eurographics Symposium on Parallel Graphics and Visualization 2011"
Are you going to Eurographics as well? I'll be please to meet some of my readers so drop me an email and join us for a community drink!
