I found it to be a great initiative, so I decided to join and draw for 21 days. I started one week leater then others, but I managed to catch up the rest during weekends and now I can show you (almost) all my collections of 20 drawings (almost, because the greedy crew of lynda.com made a bold sabotage of the event and locked most of the instructional videos before the event's end :< Because of that I miss day 20 challenge).
Day 1 - The cat's meow.
Day 2 - Drawing the line.
And vectored:
Day 4 - Give yourself a high five.
Day 5 - Refinement drawing.
Day 6 - Get cubistic (ok, I know... It's not as cubistic as it should)
Day 7 - What do you like? (Unicorns! Yaaay!)
Day 8 - Drawing a light source.
Day 9 - Man-made drawing (an espresso machine and a house).
Day 10 - Doodle sheet.
Day 11 - Draw a monster.
