Today I learnt about these interesting tools:

1. Metro Studio 2 - a collection of icons and tools for creating and manipulating icons for your favorite Met.. um.. Windows App Store! development project.

2. Monkey - a cross-platform development tool, that is actually a descendant of a tool called Blitz Basic I came across first on the Amiga way back when..

3. PlayUp - use this free Windows utility to convert free objects from the Trimble Warehouse into a format which Unity3D can use. Thanks, Jamie Fristrom!
