[visionlist] PsychoPy: beta testers required

[Jon Peirce]

Beta testers are required for PsychoPy (http://www.psychopy.org), a free 
library for running psychophysics experiments in Python.

Python is an excellent high-level open-source scripting language. It's 
neater than Matlab, under constant development on all platforms and it's 
entirely FREE everywhere. (For those making the switch from Matlab this 
website should help: http://www.scipy.org/NumPy_for_Matlab_Users )

PsychoPy uses this excellent language structure combined with OpenGL 
graphics to generate a wide variety of psychophysical stimuli in 
realtime. It has been under development for the last 5 years and is now 
fairly stable, but I need beta-testers to find the bugs that I haven't 
come across yet.

The library already contains the necessary routines and classes to run 
most standard psychophysics experiments (I've been using it in my own 
lab for several years). More importantly, it's really easy to extend 
because it comes with all the source-code (for PsychoPy and all its 
dependent packages).

A feature list is provided below. For further information and to give it 
a go visit http://www.psychopy.org. But please let me know how you get 
on so I can improve the package.
Thanks and enjoy!

Features
   * Platform independent (tested on Win32, OS X)
   * High-level powerful scripting language (Python)
   * Simple syntax (see the demo code)
   * Freeware (and based on totally free libraries)
   * Uses hardware-accelerated graphics (OpenGL)
   * Integration with CRS Bits++(for 14bit luminance resolution)
   * Integration with Spectrascan PR650 for easy monitor calibration
   * Simple routines for staircase and constant stimuli experimental 
methods as well as curve-fitting and bootstrapping (these are not the 
only things you can do - they are just the ones that I've included so 
far within the package)
   * Simple (or complex) GUIs via wxPython
   * Easy interfaces to joysticks, mice, sound cards etc. via PyGame
