I have an idea for a challenge badge or two as well. Bob always says “every season we have a crazy day” where he paints something totally different. How about a “Let’s get crazy” badge for painting one of his “crazy day“ paintings? And a “totally crazy” badge for painting all paintings he deemed crazy, or at least the crazy day painting from each season? Could even do a “half crazy” badge for getting half of the crazy paintings done. It would be motivation to get out of my comfort zone for sure.
Of course this would take a bit of work in cataloguing which paintings were deemed “crazy” by Bob himself, and perhaps showing that on the site somehow too. Work which I haven’t done…yet!
