My name is Antonio, I’m italian but living in Spain (Gran Canaria). A part from working in IT, I’ve spent years teaching Acoustics for musicians so I have a huge interest in physics simulations for didactic purposes. I'm working on an Animated Guide of all Blender Parameters, you can see it on my website www.blenderplay.com
