This DIY control of brightness change is not a linear change, but uses the following formula

Where x is the number of milliseconds since the start. The plotted curve looks like this

Sea glass is discarded glass (such as wine bottles) on the beach that has been polished by the sea for a long time and has lost its edges and corners and become as smooth as pebbles. Here it is used for decoration to enhance the effect of light.

That's what it is. In the past, the environment was damaged by littering of wine bottles, and it took decades of nature to repair it and become sea glass.

Hahaha. I was also attracted by sea glass. I thought it was some high-tech new technology product. Hahaha, it turns out to be glass from the sea, referred to as sea glass~ It seems that naming is very important~

What is sea glass? This is the first time I've heard of it. I've seen people say it's something from the sea, is it really glass?

Seawater washes glass fragments, and after a long time, the edges are worn away to form sea glass.
