Bruno Dilly of ProFUSION Embedded Systems announced EPhysics today to the Enlightenment developers list. EPhysics allows for physics effects to be added to EFL.
EPhysics doesn't implement its own physics engine from scratch but wraps around the Bullet Physics library. The most well known implementation of EFL is now perhaps through the Tizen project and EPhysics will be working its way here soon.
Those interested in learning more about EPhysics can see the message on e-devel. There's also other information on Bruno's blog. Embedded below is a video of this physics implementation for Enlightenment's EFL.
