Hey! Here’s an litte update on the Domino Design. What first came into my mind is what you can see in the left on the picture of this update. It would have worked but I quickly dropped that design and went for the 2×4 flat tile and the 2×2 inverse tiles. This combination looks elegant and works very well for domino runs. They are easy to set up in an upright position and allow to corner sharply. You also can variate the distance between them easily. I don’t know if you can do all techniques compared to other dominoes. My experience is they push over very fast because of their smooth surface. I also like the sound they make when falling over a lot.
