FF Speak

I love this new font, FF Speak. From fontshop.com:
FF Speak™ is a rounded sans serif from a new FontFont designer, Denmark’s Jan Maack. With FF Speak, Maack wanted to capture the tone and voice of youthful conversation. He created smooth but lively letterforms that would evoke different intonations depending on the weights and ligatures used.

The ligatures make me giddy! Buy it here.
