My Dilbert mask I made from scratch

This is a foam and felt dilbert mask I made a few years ago.. It was my first crack at making something special for Halloween. The think is it went over so well I am now expected to come up with something better this year. Any Ideas? Must be Office / Work freindly..

Here are some more pictures of the costume and some building instructions: http://www.instructables.com/id/Easy-Dilbert-Costume-Just-Glue-Foam-Felt/
