Creating art with code


I am looking for ideas to have a project based activity for children to create an art piece with code and make it 3D. I was thinking about using artist and then having the children design, plan and execute a drawing. From there I want them to create something that is 3D. I am thinking about using Strawbees, or K’Nexs to create the 3D art piece.
Any ideas or suggestions? I am under pressure to produce a plan to get this done beginning in January
Thank you . . for any assistance!
