Four-year-old Z. is frustrated to discover that his different construction toys are not interoperable.

Z. needs the Free Universal Construction Kit, a collection of nearly 80 adapter bricks that enable complete interoperability between ten popular children's construction toys. The Kit was conceived and developed by F.A.T. Lab and Sy-Lab in partnership with Adapterz LLC. Complete information about the Free Universal Construction Kit can be found at fffff.at/free-universal-construction-kit.
