During the first Cryptoparty in Lithuania we will learn about Tor (http://torproject.org) from wfn, who is a Tor contributor. We'll learn about the Tor software and the network, try to use it, talk about censorship on the net and the use of Tor to circumvent it. If time allows, we'll learn how to start a Tor bridge.
In Lithuanian, although you can surely ask in English. There'll be a local Hack and Tell event afterwards: http://www.meetup.com/vilnius-hack-and-tell/events/162598722/
