very inefficient, do it in a shader

Was that directed to me or op, both maybe?
I'm pretty new to graphics programming (not programming in general), so i don't know how i can do it in a shader.
And i don't need efficiency since I'm just creating something fun for my GF.
It has a max of 15-20 2D ...

Hi!
Is it possible to get this working over 2d objects too?
If yes, how?

Thanks in advance
