Little Vegas

I was at a flea market looking for legos. I couldn't find any
but I found this silly hat with blinking leds. The leds were in
three colors: white, green and blue and they blinked in three different
pattern. So I bought it to get a lightshow for this gamebooth.

Transparent lego pneumatic hose for keeping the leds in their places.

I thought I could manage without any soldering but then one of the
powercords came off and I had to open the batterybox and solder it back.
