MrTrick made a star map:
Now that Christmas is over, most of us have gone back to work, and the decorations are being packed away, the fake Christmas tree is likely to use up the most space in storage, and you only use it once a year! It’s a shame to throw it away, but what other purpose could a fake Christmas tree have?
I hacked my old Christmas tree apart, and built a massive (seriously, this thing is 2m wide) Star Map with an pretty accurate view of the southern skies, including the constellations.
There are thousands of points of light from optical fibers and white LEDs, and an integrated RF module controls the stars and the appropriately red mood lighting.
It may not be as accurate as a planetarium, but who has a planetarium hanging above their head?
