At work we are throwing a Cyberween day - basically cyber security awareness and HALLOWEEN mixed (both scary ;o) Below are some ideas I have been saving to add the "icing" on the theme... Hope they give you some inspiration too!
How cute are these! Found on MarthaStewart.com (link). We are going to use these to put around the buffet room - kinda gives you room to decorate from the ground up! Site has easy template, though I am anxious to survey my Cricut collection to see if it has a mouse and I can cheat!
