Hi.
My name is Kristoffer im 25 and from norway,
im a music producer and DJ, and i LOVE to decorate my music studio with neon / led lights dansing to the music i make!!
i've always been fan of the "Audio Spectrum" in my music program and i got an idea.
here is an example of a audio spectrum that somebody made (googled it)http://i01.i.aliimg.com/wsphoto/v0/739949665/24-16-BGR-LED-font-b-Audio-b-font-Digital-Level-Meter-display-font-b-Spectr…
How about using a peace of frozted glass: http://www.tigerglasses.com/UploadFile/201239155950%E6%97%A0%E6%89%8B%E5%8D%B0.jpg
and attaching some led lights on the edge of the glass in different colours like (low freq in red, mid freq in green and high freq blue)
Now i dont know about the electronics but thats where you come in, maybe you have some ideas on how to drive this, make it work / smooth!! 
finaly, problarly 3D some nice edges to go arround the glass to protect the glass itself.
realy hope you can look into this and hopefully make it!! 
btw im a REAL fan of The Ben Heck Show watch it every day (seriously)!!
