A pose-able tree made up one one sprite and clones. Hover you mouse over a branch and press space to add branches. Then, click and drag parts to rotate them. Also, press 1, 2 or 3 while hovering over a branch to change its length (and costume). For best results, run in turbo mode! In a more technical sense, the tree consists of a data structure comparable to a "tree" Each clone references the position and the direction of it's parent branch to calculate its own position, allowing for a tree of any size (in theory).
Not many changes were made with respect to my linked list snake (that is, in terms of blocks). I have kept these two project separate since the underlying data structures are vastly different in complexity.
