Thank you for this but..i am new and I dont know how to add credits.I would have surely added your links and whatever.But can I just simply use it for my project without any copyright or anything? pleaseeee

@IamAdev: You must credit Amon if you use it. That means in your project you must:

1. List the title (Coloured Squares - Cubes),
2. List the author's name (Amon),
3. list the license it's under (CC-BY-SA 3.0),
4. include a link or URL back to this page.

This is true of any other assets you want to use that fall under the CC-BY-SA license. Furthermore, any modifications you make to this asset must also be shared under the same license. See the FAQ "how to credit" for some advice on how to credit.
