This is wonderful and impressive. For others curious how long it took: judging from the first commit on GitHub (https://github.com/nineties/amber/commit/bdb49d27968d6bc458827394d4a9d6779adcb9ba https://github.com/nineties/amber/commit/bdb49d27968d6bc4588...), which references a first commit from 2009, it seems at least 6 years.
