These are not the Stones you are looking for

 On Monday May 13th, I placed my r2d2 rock just outside our Computer Consulting firm. To be honest, I wasn't happy with the way this one turned out. Experienced a bit of flaking with the white paint, and sealing it didn't help. Maybe that's why this rock hasn't been re-homed yet. 

Edit: Rehomed, no longer at this location
