Fluidsim 4 -
You need real hardware connection, 3D layout, or free/open-source software (look into Libra or HyPneu demo, but they are less user-friendly). Sample user quotes: “FluidSIM 4 taught me more about pneumatic circuits than a semester of lab work – because I could instantly see why my circuit was wrong without blowing a fuse.” – Automation student “The interface feels like Windows 98, but the simulation engine is rock solid. I keep coming back to it for quick checks.” – Maintenance engineer
You want a modern UI, more components, or plan to use it professionally for several years. fluidsim 4

I don't think I'll get past the fact that *The Hobbit* has the wrong tone in nearly every single scene: dramatic and scary where it should be adventurous, or silly where it should be miserable (as when they enter Mirkwood). Not to mention about half of it is an advertisement for a trilogy I've already watched.
But hey, at least it isn't about Trump.
