After downloading the laptop from the WR website, scanning, applying all automatically created offers and evaluating it, the following code:
CellPrint[ Cell[BoxData[ GridBox[{{ButtonBox["January 2003", Background -> RGBColor[0.4, 0, 0.4], ButtonFunction -> Null]}, {GridBox[ Prepend[monthlayout[1, 2003] /. i : (_Integer | _String) :> ButtonBox[i, Background -> RGBColor[1, 0.6, 0.8], ButtonFunction -> (FrontEndToken["New"] &)], alldays /. s_String :> ButtonBox[s, Background -> RGBColor[0.8, 0.2, 0.6], ButtonFunction -> Null]]]}}]], "Output"]]
displays a clickable calendar that opens a new laptop when you press a button any day
