Graphing the differences in the pieces on a LEGO panel was very clever!

This article also reminded me to "zoom out" on a design. If it's super confusing at that level, it probably still needs work. The ventilator example suffers from this a bit. It is really nice to have the instructions inline with the dials, but the visual design makes it look more complicated. If you imagined the LEGO-version, it would have more symmetrical color blocks and alignment. I don't mean to pick on them too harshly, sounds like it was made and distributed in record time!
