For my last project in Interactive Art, I ended up creating a house of nostalgia. The installation consisted of a cardboard box house, spray painted with a multitude of colors, filled with miscellanious toys and items from my childhood.
Behind the house was a framed monitor and Mac Mini, and to it connected a Leap motion sensor and projector. The Mac ran a program I created that began with a static blue background with moving white spheres. (This was intended to look cloud-like.)
