Once you get passionate enough about PowerShell to start looking for swag, you know you have a problem. Unfortunately, there is very little available in that regard. If you haven’t seen /n Software's sticker yet, here’s a bunch of people that picked one up while the promo was live. I haven’t seen anything calling out the end to the promo, but the page generates an error when you visit now.
If that still doesn’t satisfy your craving, then you might have a real problem and consider making some yourself.
Luckily, I know people that know I have a problem, so I have been getting some unique gifts lately. The first is a coffee mug. You can get mugs with paper blanks at many stores, and all it takes is a little artistic talent to complete the picture.
