A subtle tilt effect for images. The idea is to move and rotate semi-transparent copies with the same background image in order to create a subtle motion or depth effect.  Demo  Tutorial

The Bosque programming language is designed for writing code that is simple, obvious, and easy to reason about for both humans and machines. The key design features of the language provide ways to avoidaccidental complexity in the development and coding process. The goal is improved developer productivity, increased software quality, and enabling a range of new compilers and developer tooling experiences. 

This series of articles show "how" to achieve architecture with decoupled infrastructure concerns so that the end solution is simple to follow and maintain.
