An automatic sliding trigger, a self-locking oodammo magazine, and a vertical magazine all in one. There's not much more you can cram into a gun of this size. The oodammo magazine has a block trigger to hold the mag pusher when not in use, and the magazine can also be tilted back, flipping and locking without the need of rubber bands. The vertical magazine takes four green rods with ease, and can even hold five on a stretch. The sliding trigger moves without the aid of rubber bands. The handle is incredibly comfortable and fits naturally in my hand. I could go on forever about how incredibly well it functions, but I'll cut to the chase: 'Bloom' is a statement of a secondary in a K'nex war - incredibly reliable and adaptable.
Hopefully, there will be a video soon, and maybe even an instructable if there is enough interest.
