That's awesome! There's a nice desktop software app called "Shadows" which you can download at shadowspro.com which will draw all those sundial lines for any combination of walls and angles you might desire. I also have a little analog projector I assembled that will 'paint' them on a wall (intended to be used at night). It's very simple in principle: you just project from the gnomon at 15° intervals.
So I'm up a little early today (early for me) because I'm teaching my "Sundials" workshop. You didn't know I was doing that today, right? Just one of those wild coincidences... After my alarm went off, I cleared my head and said to myself "time to think sundials!". Then I rolled over and checked my phone for NavList notifications. It said "Sundial" (your message). I had to check to make sure I was really awake. Ha! More later...
