Blender

I’m not talking about your everyday kitchen appliance. This is a freeware, opensource 3D graphics designing software (www.blender.org). I first read about it when I was doing research on making a presentation for my Engineering Management class. I learned some use of it from video tutorials by www.blenderunderground.com which are simply awesome. My basic idea to learn Blender was to give an image to my ideas. Stopped leaning it when the study curve got a bit steeper. Now that I have some free time I thought of resuming what I started.  Its free and some research groups at universities are also exploiting its opensource nature.
