Scrappy Pen Plotter

I decided to try to build a pen plotter. Using an Arduino with CNC Shield, 3D Printer spare parts from Amazon and some aluminum profiles.
I am not sure if I am happy with the result. As more often then not, I regret building yet another bulky thing which takes up a lot of space and isn't that useful. Need to find some place to put this thing. also, 2 of the "rails" on which the thing slides around arrived damaged. I ordered new ones, but they didn't arrive yet. The lines should get a bit more straight with the new rails.
I am thinking about what I could use this thing for. Maybe I could create some nice geometric patterns. I am not sure. Post a comment if you got any ideas for me.

The Arduino runs grbl. Here's the grbl Github Project:
