With flickrspinnr 0.4 a stand alone version has seen the light.
As before, you can use it as a WordPress plugin, widgetized or not.
With this new version you can use it on any static page as well, provided of course that you have PHP 4.5 or later at your disposal.
Some bugs in the PHP code are stamped out by Headzoo, the PHP guru of the project.
If you already have the plugin version 0.3, do get the updated 0.4 over at Headzoo.
