Tweetwow. Those are awesome! Bumblebee was lookin a little thin, but still unreal!
We just got my daughter some 3D sidewalk chalk for her birthday. Maybe she'll be crankin some stuff like that out this weekend. I don't know though. She tried it out, and said it doesn't work. I'll have to show her these so she'll learn it's all on the artist.
thanks for postin those! very cool!
