Signal \ Slot experiments

A Short screencast showing how widgets can be visually connected, i've always liked node-based or "graphical programming" software like PureData, it allows even non-programmers an easy entry point, and saves time typing, besides the obvious eye-candy. Next step would either be the A* algorithm, so "patch cables" would go around widgets, or maybe use curves and drop-shadows to fake them being "on-top" (check this link for a cool sample)
