The Toolkit
This toolkit provided size-aware dynamic text replacement (while preserving animation), was capable of changing global colours for a variety of backgrounds and elements, allowed sets of various text and graphical elements to be enabled or disabled at will, and let product photography be swapped out as needed – really letting the (Adobe) sparks fly, creatively-speaking.
Dynamic Text Styling
An interesting feature of this toolkit, technically speaking, was allowing for multiline text to be swapped out live while having certain portions of text be styled differently (say, in a big ol' text box with animated font treatment).
The end result is something that looks simple but took a fair amount of heavy-code lifting behind the scenes to achieve.
