@Mr.Wizard, nice. Your strip3 is what I would use.

@bills, it would be an interesting challenge, but probably great fun to play with once it was done!

@Mr.Wizard, thank you - I think "trounced" is an exaggeration though! - as you've pointed out the code may be concise but the algorithm is inefficient for large imax.

comment How many Christmas gifts?
@belisarius, I was tempted to try and make it syntactically correct but a) it was too difficult and b) I had wasted too much time on it already!

Great find by the way. I wish we could get documentation for some of the useful stuff in these hidden-away packages.

@belisarius, it's in the definition for Region`BoundedParametrization

Check this: Region`RegionProperty[Polygon[{{1, 0}, {0, 1}, {2, 3}}], {x, y}, "FastDescription"]

comment How to create effect like Van Gogh's stroke brush?
@Peltio, I think one would need to segment the different parts of the image like shrx did. It might even be possible to measure the colours in each component and create the image entirely from coloured brush strokes.
