Elemental Percussion is the 2nd of 4 audio visual sculptures. When all 4 sculptures are sold it will unlock a video of all of the sculptures coming together creating a piece of music. There will also be a bonus VR180 gallery video with 3D sound. The winner of the first sculpture will also receive a 3.6m x 2m Hologauze screen. The individual sculptures are optimised to be projected onto Hologauze® so creating a large floating hologram effect.( HD video projector required) http://holotronica.com
