Automated Light Painting

I'm interested in arts (especially Street Arts) and also photography.
Most of the times, street arts change the environment of where it is created and unfortunately these modifications aren't keeped for a long time (erased by other artists or municipality)!
Light Painting made street art more fugace than it is already and also infinit because picture could be stored for long time !
I really like this duality and so would like to work on it adding my maker approach of it !
So, the aim of my project is to create a system able to reproduce drawing made on vectrorial drawing software (like inkscape for example) using light painting style
In fact, it's a 2D moving system (2 axes) with RGB leds to reproduce a maximum of color.
The movement of leds will be controled by a system able to recognize vectors of drawing and translate it in movement for stepper motor (it could be a GRBL based system).
There's a lot of knowledges on this project :
- Mechanical structure
- Electronic design
- Programming
- HMI
The mechanical structure of this system will be the easier part for me regarding my technical background.
But it's only 1 of the 4 steps ...
NB : A possible evolution could be a reproduction of drawing made on tablet or phone, digital painting of vectorized picture
