At the time it was discussed quite a bit on HN:
Nice. What were the other experiments you tried doing besides snowflakes? Any reason they didn't work out?
2012 - Virtual snowy field to plant trees and post a wish on them. A couple hundred trees planted.
2013 - This one, drawing postcards. Thousands drawn.
2014 - Live streamed a Raspberry Pi printing wishes posted on the site. 8 wishes posted. Great ROI.
2015 - Creating animated swirling "stars" drawn using spirograph patterns. A couple hundred created, later adapted to my app Spiralflow: https://apps.apple.com/us/app/spiralflow/id1086402345
2016 - Cutting out snowflakes from paper. Less than a hundred made, experience of making them wasn't great.
2017 - skipped. Had an idea of making a Christmas-themed game similar to http://www.decisionproblem.com/paperclips/ but couldn't build it in time.
2018 - One last experiment: "baking" and decorating gingerbread cookies. A couple hundred made.
That was it. I don't plan to build anything this year.
