Start with an existing image on your tablet, or take a picture of a person or a scene. Then by tracing over it before removing the original picture, you end up with a great looking sketch. With "Traces" one can look like the next Picasso! Create astonishing caricatures and artworks that are clearly hand drawn and not computer generated. Save your creation on your tablet or share it with your friends on your social networks, by email, or via Bluetooth.
Create avatars for your social networks images, or draw a preview of a remodeling project, or ... The possibilities are endless and only limited by your imagination.
