Need Help Setting Up Desktop Plz

I can’t for the life of me figure this out, and I was really unsure of where to post this question.

I see screens of peoples desktops where they have the icons across the bottom of the screen “floating” above a reflective surface, and for the life of me I cannot figure out how to do this. Can anyone lend me a hand in figuring this out?

Thanks in advance.

Something like what is at the bottom of this screen

moved to Applications


Take a look at the “cairo-dock” program. It’ll give you that dock!
