Thanks for these wonderful renditions. Can you figure out how to make the "OC" pop just a little more without overtaking the rest of the image? We often get people who ask what our symbol stands for, you've made it pop quite a bit.
Can you also revise #108 so that the (symbol-chain) are switched in where they cross. Traditionally, the bottom link always formed a "C" and the top link formed an "O". Not sure if it is possible in this design.
