The lights get pretty bright, not blinding or anything but you can see them in the daylight and when the lights are off the ceiling gets illuminated by the LED pulses.
About the beer, haha: I actually bought the caps off of Ebay to get the colors I needed to make a flag. I hadn't started a collection and wanted to build it over vacation. I have a collection started now though! :thumbup:
I finished my next project, which was an infinity mirror. To summarize, an infinity mirror is a box that gives the illusion of being much deeper than it actually is using a regular mirror and a two way mirror with lights in between. In this case I used a 50 RGB LED string that I can program using an arduino.
