Cool and thanks for the link!

I like the picture of the AK shockwave, pretty interesting if you ask me.

"Figure 11. This full-scale schlieren image shows the discharge of a .44 Magnum revolver. Two spherical shock waves are seen, one centered about the gun’s muzzle (the muzzle blast) and a second centered on the cylinder. The supersonic bullet is visible at the far left. This weapon produces a bright muzzle flash and a cloud of products of gunpowder combustion that envelops the hands of the shooter. Such high-speed images help forensics experts understand the transfer of gunpowder traces to the hands when firing a gun.

"Figure 10. Color schlieren and black-and-white shadowgraph techniques capture similar information but emphasize complementary details. A microsecond color schlieren photograph (left) captures an instant during the firing of a .22-caliber marksman's pistol. The air shock wave and the transonic bullet have left the muzzle, followed by the propellant gases. The muzzle blast is the "bang" that one hears upon firing a gun. Toward the right side of the image, thermal convection rises from the gun and the shooter’s hand. A frame from a high-speed shadowgraph video (right) shows the firing of a single round from an AK-47 submachine gun, with its spherical muzzle blast and supersonic bullet trailing oblique shock waves.
