Cake is 9x13 yellow cake filled w/vanilla bc frosting and fondant covered. Screen is a laminated photo of birthday person's actual screen saver "glued" to foam core board using piping gel, then covered with fondant. Keys are all fondant.

To "attach" screen, I inserted 3 dowel rods from the bottom through the length of the foam board. I left just enough sticking out to insert into the cake. Screen was measured incorrectly, so it's a little disproportionate to the cake :-
