The topper of this cake was four tetriminoes joined together by magnets to form the initials of the couple, J and C.
They were then to fit the individual pieces into the spaces on the wedding cake and then the cake would be served up!
The Groom said in his speech that this Wedding Cake will go down in history as the cake that will be cut side ways, as the levels are solved and "disappear". :O)
It was a satisfying moment for me for my quirky idea to finally materialize.
