Interactive Video

In 2008, I made an interactive video in which you could build a list of ingredients for a juice by selecting them right inside the video.

因为视频是实时“编辑”的, the chef could make a juice with just the ingredients you selected (your custom recipe).

The whole experience was pretty smooth: it even had background music in sync and correct ingredient order. 正如人们所说，这段视频“既真实又神奇”."

This interactive video helped me land my first job at an advertising agency.
