The LosTechies crew and I were never able to get a calendar or t-shirts or anything else made for the SOLID Motivational Posters that I put together a long time ago.

Looks like a pretty good collection of principles and pictures, including SOLID. Nicely done NimblePros team! I’m happy to see that someone took the time to do this.
