Hi, so, me and a friend want to make an animated PC wallpaper similar to the banner girls from Blue Archive. Basically.
>Character just moving around
>Character gets happy if you move the cursor around their her head very fast
I know about programing and he knows about animation and drawing, so I think we got the skills, I just want to know what kind of tool, programing language or framework I need to achieve this.

Thanks in advance.
