What can you do with a 3d printer, some sugru, and some shock cord? Hang a garland on a brick house, of course!

Print several clips, and paint them to match your house. Use some sugru to glue them on. Knot and loop some paracord through the hook and around the garland to hold it in place. More detail here: http://swampcastle.blogspot.com/2012/01/garland-attached-to-brick.html
