Well, we did it ourselves, but still it’s nice to note. Look mostly at other projects - we support the open-source, free-for-everyone platform of NumPy/SciPy and we’ll promote PyPIV (or should we call it PIVPy?) as much as we can.

Dear users of URAPIV, PyPIV and just readers. We apologize for inactivity, but it is simply due to time constraints. Those of you who wrote an email noticed that we:
a) replied within a day or two
b) helped with any problem you had
c) supported your downloading/running/evaluating problems
The blog inactivity for you means only one things - it’s good - we get too many questions, e-mails and downloading counter is crunching almost every day 
We got downloads from Argonne National Laboratory, Penn State, Michigan, Georgia Tech and so on and so on. Not mentioning that Tel Aviv University is now overwhelmed by PIV applicatons and URAPIV is one of the main tools there
If you're looking for completely free solution for your PIV needs and you're not satisfied with our URAPIV or PyPIV projects, you can download GPIV - GPL, ANSI-C package (also on the Sourceforge.net) with acquisition, analysis, all in one package. Good work:
There are two main sources of information for our users that want to join us in the move from (we stress out that the move is not complete move, we keep URAPIV development and support) URAPIV to PyPIV, or in more general sense, from Matlab to Python.
Very useful set of commands in PDF format by Johnvey Hwang, aka 37 mm website - see the blog here or press on the [link] to download the PDF.
A new Wiki, called NumPy for Matlab Addicts (that we fell like ones). NumPy is a package we use for PyPIV
I want to break free …. (Queen)
URAPIV wants to break free … (of Mathworks licensing policy)
URAPIV now is also*
PyPIV, where Py is for Python (http://www.python.org)
* means that we are not going to drop the Matlab toolbox, but in parallel we are going to enter a new field: ABSOLUTELY FREE OPEN SOURCE PIV ANALYSIS (as they say think of "free as beer"). Even kids in a primary school in Gana can do PIV now - it's free as Python programming language is free, it's free as Python Imaging Library is free, it's free as Scientific Python is free.
If you install totally free OS for human beings - Ubuntu (or any other Linux distribution), you have Python built-in
If you have Windows, download an excellent distribution from Enthought Inc. and run the Windows installer. You'll have Python working in a minute.
If you're in Mac OS X, we still have not tested it, but MacPython is there and Fink is there, so it should be straightforward installation.
Happy PIVing to all
Here's a screenshot of PyPIV on a PC with Windows XP and Enthough Python at the background:
