1. Marquee and illuminationThe marquee was done using the Gimp and Inkscape, and printed on several paper quality A4 sheets. I've cutted a sheet of plexyglas and glued the printed logo using glue in spray to avoid bubbles. Illumination is done via a small neon light of only 15 W and is more than enough to give a good result.
2. SoundThe sound system is composed of a small amplifier + subwoofer connected to 2 satellites speakers for a total power of 14 W. The sattelites speakers are protected by 2 old round grids from an ancient car stereo system.
