The Boomba Tree was a preview agent for The Canopy, with graphics by Moe and coding by edash. The dispenser creates a seed, which if it lands in the right conditions will grow into a beautiful flowering tree. The Boomba Fruit which grows on the tree contains antihistamine. The wood of the Boomba Tree is particularly resonant, and if hit they can be played like a drum. The Boomba Tree was released in May 2004, and is available to download from an archive of edash.net.
