Photoshop Pocket Brush
This set of brush presets emulates the popular Pentel Pocket Brush Pen. Unfortunately, this kit (as of version 1.0) is limited to Photoshop for the time being. These brushes make critical use of Photoshop's Live Brush Tips, a feature unavailable in any other major software. They simulate brush bristles, instead of using a brush stamp tip.
Pocket Brush and Pocket Brush Low make use of Pen Tilt to emulate the shape of the pen, and the texture of the Pocket Brush Low uses pen tilt for it's depth, so make sure that you use a tablet or tablet monitor with pen tilt for the full utility.
Pocket Brush Inker, Pocket Brush Low Inker, Pocket Brush Fineliner and Pocket Brush Low Fineliner all use the Live Brush Tips, but with the brush pose locked to straight vertical. Pen tilt does not matter on these presets, but they will still drag tails out appropriately based on pressure.

I'll be continuing to finesse versions of these presets for other software in the meantime.
