The folks I used to work with (back when I had a day job) gave me a parting gift. Burgees.
We had a stack of three we'd use for festive occasions:
The Whitby-Brewer pennant.
The SSCA pennant.
The West River Sailing Club pennant.
Now we have two more to go with those.
The big black flag has the Cloud Custodian logo.
Underneath that, in light blue, is the Python language logo.
