Where did you get your theme?
Where did you get your cursor?
How did you add the streampad music player?
How did you do background with the falling Deathly Hallow’s sign?
The background color is part of the theme, but the falling deathly hallows sign (I drew it myself) is part of a code I inserted in to the html of the theme. All you gotta do is search up falling objects html on Google, I recommend these links
You should be able to figure it out.
