People should take notes from Rodrigo Piwonka. Sometimes it doesn't take a lot of huffing and puffing to design something unique or sustainable. Sometimes it simply takes looking at something that was made for one purpose and imagining what else it can be used for.
Don't beat yourself if you can't channel Rodrigo Piwonka's fresh eyes. It's harder than it sounds. In the meantime, maybe you have a CD spindle lying around that you can use to take your bagel to work.
