Combine room-temperature Baileys and Kahlua in bottom of an apertif glass or larger shot glass (this will represent the Earth). Combine Orange Vodka and Blue Curacao in a shaker cup over ice. Chill thoroughly. Using the back of a spoon, carefully layer contents of the shaker cup atop the Baileys/Kahlua mixture (this will represent the sky). Top this with 2 or 3 small dollops of whipped cream (representing the clouds). Finally, add the cross-cut tip of a mint leaf atop the whipped cream (this represents the 'hang glider').
