Hi all, I'm sure many have asked similar questions before, but here I go anyway. I am designing an exhibition where I would like to project a skyline silhouette on to the walls of the exhibition space. The exhibition has a Tivoli/funfair theme, so the image would feature moving rollercoasters, ferris wheels, etc. The effect I'd like to acheive is a kind of 'moving wallpaper'. The lighting levels within the space will be fairly low with more concentrated lighting on exhibits themselves. I'd like to keep the wall colour dark (a dark gray or black would be ideal), so my question is: How effective would a high contrast silhouette projection be on a dark wall surface, and how best to achieve this? The resulting images don't have to be very highly visible as they constitute a background, mood setting image - it's ok if the effect is quite subtle. I have also considered using gobo's, but this is only good for rotating images (ferris wheel for example). Any advice anyone can offer is very welcome! Many thanks, Daniel.
