I am posting on my computer made from twigs, leaves and a duel core processor that I stole from a passing squirrel.
One of my still-gestating stories involves a family living in a tree-house.
No, not a house built in or on a tree, but a tree that incorporates biological (or in this case botanical) equivalents for “all the comforts of home”.
You've probably seen pictures of Baobab trees, and that's a good start. I'd need something that grows more quickly though, and whose layout could be planned.
So it would grow more like a copse of trees all growing at once, and forming walls, windows, roof and cellar.
That seems pedestrian enough, except for the possibility of really quick growth, but here's where I depart from ordinary trees.
The tree would provide illumination, with bio-luminescence. Various frequencies of glowing cells would provide the equivalent of display screens inside also.
Even music could be generated by the trees, especially nice if you like woodwinds.
And it would have internal heat regulation as well. There are plants which give off considerable heat when they are driving perfumes into the air in early spring. Measurably exothermic, actually.
Then there is the matter of waste elimination, which we will in consideration of delicacy, not delve into too rigorously, other than to say that plants absorb and thrive on our waste products, and they are natural recyclers.
Okay, what's left?
Communication.
That's a little complex. There aren't any natural analogs for plant communication, other than alleged chemical signaling.
I'll go for root connections. Similar to neuronal synapses, I'll postulate that the tree-house can send and receive signals over great distances by a means of underground telegraphy.
Basically, I'll just gloss over that aspect with a cascade of technological double-speak.

So, ... like it?
