I guess the ingenuity of the internet should never be questioned. Source Filmmaker is an impressive tool, but more impressive are the works coming out of it, made by fans. The recent videos making waves are The Turret Anthem and A Smissmass Massacre, two incredibly well-done short films that feature Portal characters in the former and Team Fortress 2 characters in the latter. Zachariah Scott has filled his YouTube page with great work, but these two most recent ones really do stand above the rest. Keep up the good work!
