Omni/multiderectional reflectors

https://en.wikipedia.org/wiki/Cat's_eye_(road)

Cat's eye reflectors are used on roads and places where light needs to be reflected directly back where it came from.

These only reflect light back in a
 very limited amout of derections.
I looked it up, and I didn't find any reflectors that reflect back in all directions, but I did design one myself. Here it is:

Grey=Mirror Light blue=Glass Blue=Light

As the light enters the glass it gets diffracted. This points it directly at the mirror, which reflects it back out the glass, which diffracts it again, and the light goes back to where it came from. If you where to look in this mirror ball, it would probably look black, because it would be reflecting your eye.

Curves

I made curves using different number sequences. Normal, Fibonacci, odd, and triangular. I used a pixel art drawing program.

Summary:
Photonics is a way to make computers using light instead of electricity. According to some scientists, it could be many times faster then traditional electronics. The basic component of photonics is, like electronics, the optical transistor, which is used to make optical logic gates, which are combined to make optical chips.

I think that it's a cool idea, and I wonder if it would be possible to use sunlight to power an optical computer. If it is, then we could have computers that never need recharging, which would be perfect for people in developing countries and remote places.

I also wonder if it would be possible to make an optical battery.

How opals are mined in Australia

The miners begin by drilling a hole into the ground, until they reach the depth most common for opals. They descend into the shaft, then break away at the rock, using tools such as pickaxes and hand drills, until they find rock with a greenish tinge. This is a sign of opals. They break the rock apart, checking every chip for a hint of opal.
