You may have caught Hollie McNish's fantastic take on xenophobia, Mathematics, but this one - about the proliferation of scantily-clad women in media - was new to me. It's actually from September 2012 so I might be late to the game, but it bears repeating in case I'm not the only one who missed it the first time around.
The woman is extraordinary.
Keep doing what you're doing, Hollie. The world needs voices like yours.
