It seems from those images, that the ones you've put more effort into, are the ones that are not performing (failing).

So true Aaron, and I didn't mean it in a negative manner, just in case it was taken that way

. I was thinking of how it may relate to the simplicity of a slingshot. Even the Joerg's creations are complex, compared to the design of a conventional slingshot, some of his designs are simple engineering, that look complex. I like the laser one the best. But you're right about failure and success. I experience failure every day with my own business, at the same time while it's slowly getting better. Embrace failure!
