Found an interesting article yesterday: What You Can't Say, which is about heresies and taboos and how to detect them (so as to open one's mind and escape from the common herd).
I have been working hard at work the last couple of days, and my brain is fizzled out. I tried to do some more two-minute challenges, and most of them were crap or I couldn't do at all. Here are the least crappy of them, the ones I didn't delete. I think this does demonstrate that my creativity is stuck in a tarpit.
