How can we make xkcd style graphs?

Question

Apparently, folk have figured out how to make xkcd style graphs in Mathematica and in LaTeX. Can we do it in R? Ggplot2-ers? A geom_xkcd and/or theme_xkcd?

Here is my take on the lines with ggplot2 using some of the code from above:

ggplot()+geom_line(aes(x=seq(0,1,length.out=1000),y=sin(x)),position=position_jitter(width=0.02),lwd=1.5,col="white")+
  geom_line(aes(x=seq(0,1,length.out=1000),y=sin(x)),position=position_jitter(width=0.004),lwd=1.4,col="red")+
  geom_line(aes(x=seq(0,1,length.out=1000),y=cos(x)),position=position_jitter(width=0.02),lwd=1.5,col="white")+
  geom_line(aes(x=seq(0,1,length.out=1000),y=cos(x)),position=position_jitter(width=0.004),lwd=1.4,col="blue")+
  theme_bw()+theme(panel.grid.major=element_blank(),panel.grid.minor=element_blank())

Not sure how to replace the axes, but could use the same approach with jitter. Then it's a matter of importing the font from XKCD and layering with geom_text.
