Caught up to day 5 so I am now done 1-6! Went for something a little different to what people might expect! I used one of the included Houdini character rigs and textured, lit and animated it! Here's my interpretation of Day 5 - Wave.
Wow these entries are so cool! Pretty new to Houdini so mine won't be! Went with more of a sway than a swing! Rendered as a flipbook! Working on catching up on 1-5 (done the first 2 now)
