If you're active on Twitter, you know about Twitter's Mirror. It's a fun experience that shows up at big events across the entertainment and sports industry. Photo subjects can even autograph their own pictures before they tweet them.

We rolled the Twitter Mirror out on the first day of Big Ten Football Media Days, and we got some great shots.

Find some of them them in this post and then follow @BigTenNetwork and see them all on Twitter today for more pictures of Big Ten football players and coaches.

Have a look at a few of Thursday's top shots.
