#MoWithLove (which Nokia has worked on independently from the Movember Foundation, with help from Futurice) will let you take a picture with the camera, or take a picture from your photo album, and allow you to add in a CGI moustache so you can get an idea of the styles that would (or would not) work on that face.
Once you've created the image, you can save it to your phone, or share it online to Nokia's own stream of moustache images, which you can also browse from the app.
Short and sweet, this is a fun app that helps the cause of #Movember, and I'm glad to see Nokia hasn't forgotten their social responsibilities.
You can grab the app and browse the shared images over on MoWithLove's dedicated website.
