I picked up these:
http://www.avery.com/avery/en_us/Products/Crafts-%26-Scrapbooking/Window-Decals/Clear-Decals-For-Windows_53212.htm?N=4294967232&Ns=Rank|0||Product% 20Number|1&refchannel=caeb1828c503a110VgnVCM100000 2118140aRCRD

They are about $15 for 6 sheets but they print really well (if you have a good inkjet printer). I have a sweet pedobear looking out my bedroom window.
