I absolutely loved this concept. I was surprised to some extent that this rubygem name is still available. Appreciated !!

this is exciting. Only Chrome24 supports it, but sooner all browsers will.

I'm running Chrome 24.0.1312.56, on Mac OS X 10.8.2, yet I still get the alert about unsupported browsers...

I also sometimes face the same issue on the same configuration. It seems chrome sessions doesnt always get support for IndexedDB. Try refreshing.
