Rakudo is a Parrot based Compiler for Perl 6.
The official homepage is at rakudo.org.
Rakudo and Perl 6 T-shirts are available from spreadshirt, Cafepress and Zazzle.
Rakudo uses a test suite to ensure quality and track regressions. It can also be used for tracking progress. The chart below shows the number of tests over time, most interestingly the number of passing tests.
Skip tests are those that rakudo can't parse yet, or dies during execution. Todo are those that run without dying, but produced the wrong result. The gray curve is the (approximated) total number of tests in the official test suite.
The same chart, this time done with Gnuplot and without stacking the values:
The number of commits (ie source code changes) to Rakudo is a fun way to measure development activity. (It's not necessarily a good way, because it ignores size of commits, time spent on debugging, and branches other than "master". Still it's something quantifiable).
On the chart above you can see the number of commits per month.
You can see that although the initial work (mostly on the grammar) started earlier, serious and ongoing development began in December 2007.
The installer and dependency tracker proto keeps a list of known Perl 6 modules that work with Rakudo. You can see the number of projects known to proto over time:
