You can buy professional domino products such as direction changers, field starters, and small to large dominoes from SpriceMachines.com. These are the same type that were used in the Incredible Science Machine events. Sprice Machines ships to the US only, but you can contact him for international shipping quotes.
If you are interested in making your own domino accessories, below are some tutorials on how to build them. My direction changers, bridges, fallwall, and lego domino template were all homemade following these designs:
Direction Changers: A spinner used to have a domino line change direction 180 degrees.

Lego Domino Template: Used to setup a straight line of dominoes evenly spaced out.
Bridge: Used to have domino lines cross over each other.
Small to Large Dominoes: Wooden planks used to knock down bigger structures such as walls, pyramids, and cubes. Here are the dimensions of my small to large dominoes:
Small: 3" x 1.5" x .5"
Medium: 4.5" x 2.25" x .5"
Large: 6.5" x 3.5" x .75"
Extra large: 9" x 5" x .75"
Jumbo: 12” x 7” x 1”
Fallwall: A giant "wall of wooden steps" used to create designs built in domino.

I hope this helped, and of course, have fun building! :)
