visit their flickr page for more downloads.
the images are fairly small (even when downloaded at their largest) so if they don't fit on your desktop you might be able to do something else fun with them, like make cards or stationary! i love the march calendar. it barely fits on my 13" screen, but it works! =]
ps- i arrived home safe from my trip. on the plane ride i read this book about perfumes. it's a great read, i highly recommend it!
