you can make your own. this is probably not the best way to do it, but this is how I did it:
good link: http://www.jigsawknits.co.uk/illusioncreate.html
-run an image through microrevolt http://www.microrevolt.org/knitPro/
then print that chart.
-get some graph paper, a pen, and a highlighter.
-chart by hand using the pen onto the graph paper by looking at your microrevolt chart and making Xs on the graph paper for all the purl bumps you want raised (see the jigsawknits link for clarification on this). all other stitches will be knit, and will lie flatter than the purl bumps. see the chart key on this one http://image.guardian.co.uk/sys-file...alienscarf.pdf
for further example of the knit and the purl.
-remember that every "slice" of your image will actually take up 4 rows
in the chart. this can result in a very "tall" chart. mine came out to I think over 140 rows tall. most links recommend trying to keep your original chart as "short" as you can.
-I then highlighted every other row with the highlighter, so I could follow my chart a bit easier.
