World without end ACMI Exhibition The first thing notable about "World without end" is the dark feel of the exhibition. Going down the escalator‚ all visible light disappears. This would be for several reasons. Most of the works are projected‚ and for projectors to work effectively‚ they need to avoid other light sources. Also‚ leaving lights off achieves an eerie atmosphere‚ and a sense of mystery. The exhibition is set out like a long hall‚ with some displays curtained off‚ creating sections

3D LED Cube The 3D LED matrix used here is a 6x6x6 monochromatic LED Matrix. There are a total of 216 LEDs. The reason for choosing this size is that it provides the best of overall cube size and a number of good patterns great displays can be shown with the help of 3D LED Cube. Mono-chromatic LEDs from well known manufacturer are cheap and affordable; usage of mono-chromatic LEDs allows easier construction and programming of Cube. With monochromatic LEDs one has the choice of four mono-chromatic
