It was interesting seeing the different approaches of creating a surface pattern with apertures. We used different offset techniques to adjust the size of the apertures and used client and server buttons to reference the same surface for each technique.
Using Client and Servers is an easy way to reuse the same serves with established attributes to manipulate it with other commands.
Of the techniques, this one was probably my favorite. This one used the MD slider for an attractor point to adjust the size of the apertures in relation to the attractor point. The MD slider helps me visualize which corner the attractor point is closer to.
