I used to have molds for chocolate bars that were molded to look like The Last Supper. They were outstanding. You can get a ton of different varieties of candy molds from the interweb for pretty cheap. Also the different flavors of chocolatey chip things they sell at the grocery store (like peanut butter or mint) melt the same as normal chocolate on a double boiler so it’s easy to do layered and filled candies instead of just chocolate.
