+### Sirkel
+
+Sirkel is a geolocation based chat application that won VMware's Flings Contest among all interns in the Americas. It was build in 3 weeks using Rails, Cloud Foundry & Pushr App.
+
+Because it was built in 3 weeks, there are _bugs_, so please just use this as a (very)rough reference.
