I've been interested in Visual Programming Languages (VPL) for a while. However I've hardly seen any environments that can be used for practical projects such as Windows apps or web services.
I've heard of the following:
- LabVIEW - electronics and instrumentation
- Microsoft VPL - robotics
- Game Maker - games
- Google App Inventor - Android apps
- Tersus - web apps
Are there any other VPL environments that generate executable programs and can be used for practical applications?
