Here's an offtopic thread dedicated for you creative individuals out there
I'll start:

CD Idea #1
Decorative Heat Shield
My bedroom/den is located on the 2nd floor of my house, with a b*i*g sheet glass window facing the west. Unfortunately, the view is not good as my neighbor's roof is located directly in front of the window. To make matters worse, my room gets unbearably hot after midday, because the sun's rays from directly overhead gets reflected toward my room, thanks to my neighbor's glazed rooftiles. And before the heat is able to dissipate, the sun lowers toward the west bombarding my room directly with radiation.
Even the airconditioner failed to bring appreciable cooling, making the dress code in my bedroom (if anyone is daring enough to stay inside) to be topless-and-shorts.
I was desperate. I was playing around with the idea of installing a car-windshield heat reflector on the window, unfortunately that will block the sunlight also, making the room dark.
My eyes wandered to a stack of damaged CD's. A lightbulb flashed on in my mind. Within minutes, I was busy glueing the CD's in a nice geometric pattern covering the window.
I glued the reflective side toward the outside, to reflect the heat rays back out, and the label side toward the inside, to make a nice mosaic on the window. As the CD's are round, they have the inevitable space between them. Add the built-in hole of the CD (plus the transparent area around the hole), and sunlight is still allowed stream in, and quite acceptably. The room is still quite bright, and the holes make nice rays when enough dust is in the air
Does it work? Hell, yes! I ran out of stock at 25%-30% covering, but already the room temperature in the afternoon drops quite noticeably compared to previously (I carefully chose the location of the CD to provide the most effective blocking). It's still rather hot, but now it is more bearable. At least the little aircon unit I have now can beat the heat.
I'm going to go around fetching damaged CD's from my friends...
