Above you guys can check out this AWESOME video of an artist from the UK who goes by the name of Kyle Lambert. Using the Apple iPad, his finger and the Brushes App, he basically recreated one of Beyonce's photos from her Sasha Fierce era. Took about 6 hours to do so.
He did a DAMN good job with this. You can basically see the image come to life with all of the details being touched in. The skin tone, eye shadows, hair colors and everything. This is pretty freaking awesome. 2 Thumbs up!
