Because of the excavation in the aftermath of basement flood many years ago, patio stones around the house gradually inclined towards the foundation. Since it is essential that rain water stay away from the foundation, my professional artist daughter Véronique and professional architect Kevin have kindly helped me in re-placing the patio stones. Here are BEFRE and AFTER shots of patio stones around my house.
Rainstorms left rain marks on the patio stones, proving the effectiveness of patio stones around the house gradually inclined away from the foundation.
Now, we can experience spatial distortion similar to the effect at Canada Science and Technology Museum's Crazy Kitchen in Ottawa, ON, Canada, at Copernicus Science Centre in Warsaw, Poland, where my geological engineer/exploration geologist daughter Évelyne was visiting, etc.
