House with Chimaeras
Due to the steep slope on which the building is situated, it had to be specially designed out of concrete to fit into its foundations correctly. From the front, the building appears to have only three floors. However, from the rear, all of its six floors can be seen. One part of the building's foundation was made of concrete piles, and the other as a continuous foundation. Usually, these two approaches do not mix well but Horodecki somehow succeeded in overcoming this technical problem.
Stalactites (solitaire)
Before the game starts, the player can decide on how the foundations should be built. Building can be either in ones (A-2-3-4-5-6-7-8-9-10-J-Q-K) or in twos (A-3-5-7-9-J-K-2-4-6-8-10-Q). Once the player makes up his mind, he begins building on the foundations from the cards on the tableau. The foundations are built, as already mentioned, up regardless of suit, and it goes round the corner, building from King to Ace (if building by ones) or from Queen to Ace (if building by twos) if necessary. The foundation cards turned sideways, though not necessarily be done, is a reminder of the last card's rank on each foundation.
