# 1) -A: render frame #1, render frame #2, ...

# 2) -o: support at least {GIF,MP4,WEBM}
|

# 3) -s: effects: rotate, smash into bricks, swirl, wave, ...
|

# 4) Feature: include ETA @ progress bar
|

# 5) Feature: autodetect video width from widest mircart
|

# 6) Feature: render mircart as 3D blocks vs flat surface
|

# 7) Optimisation: dont stall GPU w/ glReadPixels(), switch to asynchronous model w/ FBO or PBO (http://www.songho.ca/opengl/gl_fbo.html, http://www.songho.ca/opengl/gl_pbo.html)
