If you haven't seen Smiling Friends, you're in for a treat. Zach Hadel is a genius.

The mix of 2D animation, 3D animation, claymation, stop motion, live action rotoscoping, and comping in guest animators like Joel Haver and David Post amazing. You know they appreciate the art form.

I've seen the multiple techniques becoming more popular (Wabie shorts), it really showcases a dominance of your craft when you can use multiple techniques instead of overrelying on a simple one. Great comedic/expressive technique as well.

I imagine how it would be with software, you have a whole ass huge website, but out of the blue you download a .jar for Nokia and you have to run it in a nokia or a very niche VM,(Or just in a JVM). Maybe to get a 6 digit verification code so you can log in to an account.
