This is just a small observation I made recently and wanted to bring up; I'm gonna assume it's common knowledge but this is just a nice detail in the games I wanted to appreciate real quick.
(it would probably help to make gifs but I don't have the resources on me right now)
Sonic levels are always "alive." There's always some kind of motion within every stage, even if it's not the player. We all know this; the flowers in Green Hill move and bounce, the signs in Spring Yard glow, the panels in Casino Night rotate and change symbols, and so on. Even with stages like Mystic Cave where the level artwork is completely inanimate, there's lots of objects within the stage that bring it to life such as the crushing pillars and giant crates. Marble Zone almost had the animated UFOs, but it still has kinetic energy through the lava that sways back and forth.
Lets even look at Marble Garden Zone and some of its objects.

The Green Hill Zone flowers look like stylized sunflowers, but this tree here? It looks like a normal fruit tree. Of course though, the fruit is animated and swings around in the game. There's no gameplay related function for this, it just adds to the kinetic energy of the stage, giving it more life.

The swinging platforms are in a lot of levels, but they still bring visual motion to the levels.

Both the background, foreground and level gimmicks contribute to the life within a Sonic stage. Casino Night Zone is a good example of a stage that has all three. In fact, this goes for just about any level in a video game, but Sonic games had a tendency to go the extra mile in terms of animated environments.
Level themes aren't really sensitive to kinetic energy, as you can have mechanical stages full of industrial movement, or even caverns that glow. There's always some way that the levels become less static. It's all basically nice seasoning on an already great experience. Just imagine how different these stages would be if things weren't animated as they are. The beta version of Casino Night is probably a good comparison. It was obviously unfinished, but you get an idea of what a level is like without its life and energy. Things glow all over the stage, but the animated panels, gimmicks etc. had not been implemented yet, so you basically explore a lifeless unfinished shell of a level to-be. When we come to the final version of Casino Night, the city in the background sparkles, and the river reflection shines. The panels are now animated, and all the objects are in place. It's a living, breathing Las Vegas giant pinball machine.
Like I said, this is probably common sense to a lot of people, but sometimes I notice it missing in fan games or other media, so I thought the topic could warrant some discussion.
