Here's my first ever digital artwork created by my sleep, snore, bed movements, and breathing while I sleep for 7 hours. This was created via an iOS app called Ibisa Sleep Art. The iPhone captures via microphone your breathing, snoring and then its motion sensors captures your bed movements.
So the artwork shows that I snore a lot and I roll in bed too much hahahah
Try the iOs app, its fun and you create original art during your sleep.
