Seach has failed me. :( Answered

Hey all,
I'm new here, but i've made a tonne of things from this site, and always forget to register. ANYWAY, i came across something a few weeks back, and i just cannot find it again. Please please please help me.

I think i was looking for something on how to make LED's react to sound or possibly a guitar valve amp or a spectrum analyser, when i came across it. It was some sort of LED or filament bulb or something, that was being built as a decoration. I'll try to be as descriptive as i can here. The actual LED/Light thing wasn't an LED. It looked like a filament bulb, but instead of it just being a light, it made symbols, text etc etc. It wasn't like a segment led or anything led related, it looked more like a filament in it. The lamp itself was box shaped, and it looked like it was about 50mm x 50mm x 50mm. I can't even remember the name of what that lamp display type thing was. There were a few things i've come across that remind me of what that thing was. It was a bit like a display version of one square of one those old school alarm clocks where the numbers flipped down?

Sorry if this is a bit vague, i'm hoping it might jog someone's memory?
