Sandy's disk art
One of the top artists in Pittsburgh provided the disk designs shown above. See her web page, https://www.kesslerkaminski.com/
Coach Mark Rauterkus gave a break-out presentation to some teachers at an in-service event to share how we've been using both art and technology in our swimming programs in the schools. Plus, they put down some wonderful art onto the disks as examples for others to draw upon for good luck, in the spirit of the Pennsylvania Dutch.
