I'm Sarper, a GSoC student this year that works on adding new physics
based animation effects to LO Impress.
As the GSoC period comes to an end, I'm now working on preparing new
animation effects that use the introduced physics simulation
Therefore, I thought I would let you know and invite you if you're
interested in creating some new animation presets.
Hopefully the whole implementation on my experimental branch will be
merged by ~end of this week - and if you're really interested & don't
want to wait :) you can pull & build from my experimental branch .
You can check out my latest blog post  that has some example
animation effect hierarchies - and the one before that  for further
Looking forward to hearing from and hopefully collaborating with you :)
