Cinemagraph 
These aren’t your ordinary GIFs. The cinemagraph is a medium pioneered (and named) by husband and wife team Jamie Beck and Kevin Burg in which individual instants of motion are isolated against a static image. This dichotomy creates moments that are quiet and contemplative, elevating the humble GIF into something much more refined.

Use python 2.6 on CENTOS5/RHEL5 
Because CENTOS5/RHEL5 ships with a bit outdated python (2.4) usage of the 2.4 may lead to some unpleasant surprises. But, glory for EPEL, the lifesaver - has python 2.6 ready and you may also deploy virtual environment where tools as pip are preconfigured so your new 2.6 environment will not clash with the old one.
