In this project, you see the Microsoft Access logo infinitely increasing in size. The reason for this is that the sprite is constantly switching back and forth between the Access logo and a sprite with nothing in it. In case you didn't know, the smaller a sprite is, the higher its maximum size can be. The empty sprite can therefore have infinite size because there's nothing in it to reach a limit. And since the sprite is constantly switching costumes, the sprite can gain or lose infinite size without a limit.
IMPORTANT NOTES: ⮞ Do NOT use the "next costume" block when trying this. There's a visible change when using that block in a loop rather than the code in the project, causing your sprite to stop growing at the usual maximum. ⮞ SIZE HAS A LIMIT. Scratch's maximum size that ANY sprite has is 27,000. I know I said infinite, but explain to me what you'd do with something at over 200 times its normal size.
