Hi there, I has been a synfig user for about 4 months now, mainly to create gifs for a facebook fanpage and for fun.
I present to you my longest job as today: youtube.com/watch?v=q7nMwiyY0J4
I also use Blender, Gimp, Inkscape and Bash(imagemagick/avconv) to complement my experiments, I even created a C program to create a timeshift effect: levhita.github.io/timeshifter/
You can find me in imgur and reddit as “levhita”
