@Ost0: Im sure you can get a lot more led strips for the bucks by looking at ebay.
I'm not sure if you can get exactly the same kind -- and the library and examples provided by Adafruit are really, really good. There's no point in having cheaper LEDs if you can't get them to do what you want them to LOL

(American readers: if you don't understand the above, don't worry about it...insider Brit joke based on HP Sauce bottles. What - you don't know what HP Sauce is???)
Based on what you have said about the Arduino driving NeoPixels, it should not be difficult to drive your LEDs with a 5% increase in brightness as you go round - this would give you a pretty good idea whether this would work or not and what sort of effect it will give you....
@David: Ref your comments on the Badass display. I thought - why not combine the two?
O M G !!!
That is a REALLY good idea!!!
I probably won't do that for the first pass, because I already have a "vision" in mind (see my "BADASS Display Part 2" column tomorrow) ... but the real work is going to be in the electronics and the algorithms -- the LEDs are just something that go on the front -- so it would be really (well, relatively) easy to swap the display portion later ...
Way cool Max, reminds me of when I build my first Disco lights years ago. The only thing that is missing is a video of your happy dance..... :-)
Ref your comments on the Badass display. I thought - why not combine the two? Of course with this you can't control how many levels of reflection you get...or can you? If you amplitude modulate each led in the strip according to the level of sound at a particular frequency, I think the number of levels of reflection would appear to change - more for a bright led and less for a dim led? I'm sure you could do some experiments just driving the LEDs at different levels to verify this, then if it works, design the sound interface and FFT to drive them. I think that would be VERY cool???
@Duane: ...but your version is much, much more impressive.
Why, thank you Duane for your kind words. I must admit that I would be tempted to start work on a more elaborate infinity mirror if I didn't already have two mega-cool projects on the go -- my ongoing Inamorata Prognostication Engine project and my new BADASS Display project -- both of which arte powered by Arduinos and both of which boast a cornucopia of NeoPixels.
@Antedeluvian: You've got me thinking about using the adafruit strips for my street number (remember the gadget smackdown).
You could do some amazing stuff -- have them "drawing" the numbers -- then flashing them -- then doing this rainbow effect -- also it would ease you into using the Arduino... if you are seriously interested email me and I'll point you at the bits and pieces you'll need.
