Hokusai's Mount Fuji

I have done a few projects now, based around Hokusai's famous woodblock prints. Currently I am working with a Year 5-6 class to create their own version of Hokusai's Mt Fuji print. To give it a bit of a twist, the students could change the sky (some became sunsets.....others had thunder and lightning!) and they also had to add their name (in some type of calligraphic style).
