You can go to Pilot's page and submit photos of your own self-expression by clicking on the pen you used to create it - currently the options are the G-2, Precise, FriXion, or the B2P. I submitted a few pictures yesterday, as seen below! You may have seen two of them on the blog before but I really like them so I thought I'd share them again.
I think it's really fun and cool. Surely you all have doodles and masterpieces you'd like to share - I personally love seeing the work of other people!
