There are plenty of strangely shaped speakers on the market for the home theater and music fan who doesn't mind spending some big bucks. Some of the really high-end home theater speakers are designed to be more like sculpture than a box just for sound.
The latest strange home theater speakers to crop up are the Growin' Up speakers that are inspired by trees, yet appear to be made from plastic. The speakers are modular and have woofer, mid, and tweeter modules that you can stack to get the speaker you desire.
The modular design of the speaker lets you turn each component in whatever direction you want for a different look. They remind me of a section of an octopus tentacle more than a tree. The design is more concept than a real product right now. When/if these things ever make it to market, you can bet they won’t be cheap.
