Hi Zachary,

First of all. Your patch is soooo cool and really gave me so much fun. Thanks a lot!! Here I have one thought.............what if I want to set the camera in position 0. 0. 0. and only "look around" it? like stand in one position and looking around? I used "lookat 0. 0. 0." but I couldn't make camera really like "look around". Do you know how to do it?

thank you so much
