A fluid dynamics messy piece

Each edition portrays a unique tree at midnight, complete with an invented latin name. The trees are fully customisable: click on a branch to prune it; drag a branch left and right to rotate it; and drag a branch up and down to change its length. Type "u" to undo that bad crop, and to liquify the leaves, move your mouse over them.

If you're lucky enough to get a special FX of (a)ura, (f)low, (o)wls or (s)himmer, then type the appropriate key to stop/restart the effect. Please do not feed the owls.
