Heres me with my kids and one of me at my first MMA fight, sorry Im new to all this costume stuff so I have no pics of me dressed up, but thats my son in an Obi-wan costume that me and my mom(I dont know how to sew) did. I'm new with posting pics so I hope this works.
Gosh Cal, I am not THAT ugly! Kidding man...yes, it is a filter. Go in Photoshop, have an image open, go to the Filter Menu, pull down to liquify, it is right above all the standard filter options. You can get some freaky results...very trippy (or scary) HA!
