Can anyone recommend good free apps for graphic design class?

Our students have ipads and I would like to do some work using free apps.

 

Anyone have any ideas?

 

Try Richard Byrne's Free Technology for Teachers blog, www.freetech4teachers.com, which should link to his blog (the title of which I can't quite recall) that's specifically oriented to iPads.

 

Wow, this looks great. I can't wait to check the apps out. Thanks!
