All was fine but i wondered if there was a software which would help me make the animation on the computer just like i would do on a sheet of paper. One google and 5 minutes later.. i found http://pencil-animation.org/ a slick lightweight tool for making animations. I've been tinkering around with the software and have made a couple of small animations.
Btw.. you can create a gif from a sequence of images using convert command.
"convert -adjoin animcyl00?.jpg cylinder.gif" where.. animcyl00?.jpg refers to the image sequence and cylinder.gif is the output file.
