Kinda. Not the entire gun, the idea was closer to giving a machine pistol a bendi-rifle shaped stock. You only put the barrel/hammer and magazine around the corner but not the two handed stock you held on to safely out of sight. The rest of the gun shaped stock was for the electronics and camera etc so you can aim.

Those Acoustic Mirrors are pretty awesome. At the local Science center they have a pair set up across the food court area, and in a recent trip (I had not been there in over 10 years) they were still there, and my kids and I had some fun with them. You can, even with people walking between them and all that noise created by them, literally whisper to one another and still make out what the person is saying across about 100+ feet of noisy cafeteria bustle. (on a side note MEIN GHOT! that had me laughing for about 5 minutes solid.)

[@windhelmguard5295]

the krummlauf wasn't a failure. it wasn't made for "shooting around corners" it was made for tank crews to defend against infantry trying to climb the tank, the bullets fragmenting inside the bent barrel was by design as that, combined with it being on a submachine gun, generated a stream of shrapnel that would be lethal enough at close range and the low durability wasn't an issue as tank crews weren't supposed to even get into that situation.

The tribals laughed and taunted them the entire time, until the siege tower was finished. The Gauls saw the giant tower moving towards and immediately surrendered to the Romans. They believed there was no way the romans could have moved the siege tower by themselves and assumed that they had received help from the gods.

The thing with the Impulsoria was that it had gears. Due to their anatomy and body mass, running exhausts a horse rather quickly - but they can walk almost endlessly. Work (in this case, literal horsepower) is the product of (mass x distance)/time - specifically, 33,000 foot-pounds per minute. Moving 3000 pounds @ 11 feet per minute or 300 pounds @ 110 feet per minute is the same amount of work. Coupled with the fact that railcars have less than 1% the rolling resistance of a wagon on the street, the impulsoria could operate at speeds comparable to modern light rail systems! (Also without the noise and pollution of a locomotive.) Not bad for 'primitive' technology.
