make a christmas tree out of dildos,and paint the bp and hang them as ordaments, that would look cool.
hollow the dildos out and use as candle holders.
if you have a fish tank stick a few dildos and bp in there in the shape of a castle.
make the dildos into spikes for your front garden(probably would work best if you had an iron bar fence and very forgiving neighbours
get different coloured ones and make a banner saying something like happy birthday,happy annerversy,happy new year or merry christmas
and my favourite-
make a welcome mat for a friend says "please come in"(naughty but my fave
