Hey guys, here's a realistic Newton's pendulum for cycles. Hope you like it
750 samples will do fine :D
Very awesome blend how did you get the motion blur with a still image render.
I used a cycles option called... well.... "motion blur" :D I believe it's on the render tab on the properties menu. I created an animation for the ball and the wire and set the motion blur to the number of frames i thought it would work.
