`````` This week’s sketch was a rather large undertaking as it involved using objects on our own for the first time. It took quite some time to be able to properly implement an object without having my hand held through the lab but I eventually succeeded. I stumbled upon the random sail movement by accident but I loved the effect of billowing sails in the wind.
