i figure that this is a totally do-able household project when done on a smaller scale...get a cupcake mold (two separate pieces, a bottom + a top piece...or whatever shape you want), and coat twice with your favorite melted chocolate mixture. cool for about 15 mins in fridge (keep an eye out for it...you don't want the mold to crack from the cold). after you've made the two molds, fill the bottom portion with your favorite treats: truffles, wrapped candy, choco bark, small gadgets, whateva!
once you've filled it, use some more melted chocolate to use as glue and pop on the top. decorate to your liking.
