A man came up to me while working on this and said he had been watching me for a couple minutes and was amazed to see a blank chalkboard come alive like that. My thoughts exactly!
And this was before I was caught red-handed accidentally singing along to One Direction's "Steal My Girl" on my headphones. Not embarrassing at all.
Thanks, PRUMC for letting me come play with chalk! (and for forgiving me for having bad taste in music.)
