Fuels used may be derived from existing waste streams such as animal wastes and streams of discarded or unwanted animal byproducts generated at animal slaughterhouses. A method of processing organic waste products into fuel includes homogenizing the waste products. The waste products are heated and pressurized. Water is removed from the waste products. Selected constituent of the waste products are separated from the waste products into a waste stream. The waste stream is blended with a fuel to form a bio-fuel mixture.

Methods for providing drawing assistance to a user sketching an image include geometrically correcting adjusting user strokes to improve their placement and appearance. In particular, one or more guidance maps indicate where the user “should” draw lines. As a user draws a stroke, the stroke is geometrically corrected by moving the stroke toward a portion of the guidance maps corresponding to the feature of the image the user is intending to draw based feature labels. To further improve the user drawn lines, parametric adjustments are optionally made to the geometrically-corrected stroke to emphasize “correctly” drawn lines and de-emphasize “incorrectly” drawn lines.
