Bitstrips seems to be all the rage lately. If you haven't heard of it before, it's a Facebook-connected app that lets you turn yourself and your friends into cheeky cartoons that you can share with the world. There's no official BlackBerry 10 Bitstrips app for now, but you do have the option to sideload it if you want to get in on all of the comicy fun as well.
For this one keep in mind that it is a bit moody and may cause you more hassle than it's worth, but regardless, you can install Bitstips on your BlackBerry 10 device if you're feeling left out.
Again - this once is fairly buggy so you may have issues with crashes, dropped connections or long load times, but we've found that it does work enough to make a strip (to some extent at least) if you are determined enough to do it.
If you need more help or want to share your strips, hit up the CrackBerry forums for more.
