TwoHandPainter introduces a new drawing interaction by making use of multi-touch to control line width and opacity while drawing.

To draw you use one finger to move a painting cursor on the canvas. To paint the second finger needs to be placed on a control area. By changing the position inside the control area the line thickness and opacity can be changed.

TwoHandPainter is available on the Microsoft Phone marketplace. It is free for a limited time:
