During my trip, I took a lot of photos, and I have created a photo gallery for my Instagram Hong Kong pictures. The stack you ask? uwsgi, Python, Django, and I included both the TN3 and galleria javascript for the photo gallery, all running on Stackato.
Step-by-step:
git clone git://github.com/homingli/homing-hkphotos.git
cd homing-hkphotos
stackato target <api-endpoint>
stackato login
stackato push -n
