PenPressurizer is a simple tool for the Mac that provides improved control over your pen tablet's pressure sensitivity. It should work on most Wacom tablets and, of course, the Axiotron Modbook.
It does this by providing more fine-grained control over the pen's apparent hardness than is provided by Wacom's preference settings as well as allowing you to adjust both the minimum pressure required to get the tablet to respond and the pressure required to get maximum tablet response.
The interface shows the present setting's effective pen pressure/tablet response curve giving you clear understanding of what the settings are doing. Conveniently, the app runs in a small floating window allowing you to adjust the pen's behavior while using your favorite illustration or drawing program.
This is my first Cocoa related project (hooray). It is written in AppleScript-Objective-C and the source code is available at Github (http://github.com/CdLbB/PenPressurizer). Since it is AppleScriptObjC, it is Snow Leopard only.
There are a couple stubborn bugs at the moment (see below), so, for the time being, I'm making the the download below available to members only (but, of course, anyone can join the Modbookish). If you have any problems, PM me (ericn). (Update: download available for everyone. See below.)
Known bugs: Due to the unsophisticated way that this app forces Wacom's tablet driver to recognize changes in pen settings, the cursor may jump briefly after you adjust the settings. Just ignore it. More seriously, if you make a lot of setting readjustments quickly, in rapid succession, the tablet driver may freeze or die. On a Modbook, this can be easily fixed by pressing and holding down the Modbook reset button. I'm not sure what happens on a regular Wacom tablet attached to a Mac. If you experience this issue, let me know.
By the way, anyone have any good ideas for an icon? I was thinking maybe a bicycle pump connected to a pen.
Update: Open download PenPressurizer.zip
