Wow!.. fantastic experience. This is the tool I’ve been waiting for since I was 7. I remember wanting to push my pencil into the paper to make something go back into space. I was upset and my mom showed me about perspective. I was bummed that I had to create the illusion of depth. Today I wanted to put a stroke behind and in front of another … and can now just push back into the drawing. … only had to wait 40 yrs…but it was worth it.
