I like the principles but the examples are not that** excellent. With the same principles you can end up doing stuff very differently: Marttiini vs. Tommi Porche vs. Mini Walther vs. Detective special Many times good design goes very closely with good engineering. Porsche for example features a six cylinder boxer engines. They are a wet dream to anyone who likes theoretically cool engines as well as to anyone who just likes practically good engines. (self balancing and theoretically no need for flywheel, very low center of mass, and smallest engine capable of all this) That Walther pistol is theoretically even more beautiful than aesthetically. It features recoil operation, which is potentially lightest self loading operation and it has unique feature of damping out recoil. Yet the barrel travel in this recoiling motion is completely aligned with sights in contrast to 1911 style pistols. This feature gives this little beast as good accuracy as the bullet is capable of delivering.
