Aves Engine is a software development kit to generate spectacular isometric browsergames without the need for third-party plugins like Microsoft Silverlight or Adobe Flash on the end-user side. Highly inspired by Game-Engines from the PC and Videogame-Industry, Aves-Engine is aimed toward serious browsergame publishers who want to benefit from a component based engine architecture and cross-plattform compatible code to deliver on any desktop operating system or mobile devices.

The Akihabara which you can download here is my personal dream too. It is a set of libraries, tools and presets to create pixelated indie-style 8/16-bit era games in Javascript that runs in your browser without any Flash plugin, making use of a small small small subset of the HTML5 features, that are actually available on many modern browsers.
