What do you use when you want to get a fresh perspective on a problem? I sure hope the keyboard, either physical or virtual, isn't your first choice. We have a much better alternative: when you need a thinking or learning tool, a pen should be your first choice, regardless of whether it's powered by batteries or ink.
An epic quest to regain a bit of sanity. We write many words and build with LEGO® bricks to explore the bugs and features of the human condition. Safe for work.
