Sometimes clients give you a set of specifications that don't fit your standard process or product. That situation makes you rethink how you do things. Sometimes that doesn't work, but often it makes you take a fresh look at what you do and you come up with something really cool and effective. I just had that happen today. It's my Apollo 13 moment where I only had one box of parts to create an air filtration system. Or, in my case, a hard-hitting class in a shortened time frame.
