I normally want party approaches which are unconventional and out of the box. I found that Youtube is a good source for these kinds of tips. All you will have to do is go to Youtube and do a search for "birthday party suggestions" and you can find many hours worth of video clips with many fabulous advices. The trouble is, who exactly has enough time to see them all? Thus I am on a constant mission to gather some notes to save me and also hopefully others some time.
Here is an awesome video with some crazy party ideas - https://www.youtube.com/watch?v=wUlJSgYGmFw
