Make my stereo glitter and hum.

My stereo needs more blinkenlights. Point me to some neat projects I can do.
I recently refurbished a Marantz 2220B amplifier/tuner to go with my Thorens turntable. Right now it has an iPod dock and the turntable hooked up to it, but that's it, and it's kind of bland.
I have a tape monitor output and I'd like to build something that can use this to do something and sit on top of the amp.
I have several scavenge-able old units (cd, dvd player, old amplifier) to house the flashy thing. I know my way around a soldering iron, bread board and a Mouser catalog. But: I'd prefer to avoid anything that requires programming or LCD screens (given the old-school vibe of the current setup).
So point me to some neat projects so whilst I sit and listen, my eyes can rock out too.

Response by poster: Yeah, the Pulse Project is a prime example of what I'm looking for!

You wouldn't have to build anything, but an antique oscillscope (the kind with the round crt) could look pretty nice with that rig.

I fully approve of this project and wanted to offer this for inspiration!

AN6884!
This is a very simple to build 5 level volume indicator. I've built ones that use up to 130 LEDs and another ran for several consecutive months with about 60 LEDs hooked up.
Here's an example of one I built... SLYT
Usually you can have a line run directly in, but since I used mics I had to build a little transistor pre-amp.

Response by poster: That's pretty cool, cloeburner. Got a schematic?

Schematic
This is the direct line input schematic. Change the 2.2uF cap to control the amount of time the LEDs remains on... lower the value for a quicker fade.

Response by poster: Not outside my comfort zone, but possibly outside my wife's, and definitely interfering with my lease. Very cool, however.
