i know, im not as good as whirlwind or logopai, but i wanted to give this a shot

Thie should have been the first exercise I suppose. Give it a try remember to add some cushion at the ends of the swing. And stop by the Logopai boomzone for my movies and exercise.

My attempt in doing logopai's pendulum exercise :) Sorry the shadow sucks XD

Just the pendulums

A wrecking ball.
