I came upon this idea when I was running the Toys for Tots program at my job, but just now got around to trying it out. Someone had donated one of those Don't Break the Ice games and I noticed for the first time that the "ice" is just a bunch of white plastic cubes. This is extremely simple (just the way I like my customs! ), but I think the results are pretty awesome. I took the Don't Break the Ice cubes and sprayed them with a Krylon Fluorescent Cerise. They may be a little big, but for about $10 total you get a pretty decent number of cubes for your display! I included a pic with ROTF Bruticus for size comparison.
