Thomas Clarke, under the username Sparkles*, used to be the Yogscast's Audio Manager. His roles were varied, but in general, he engineered the audio in YogTowers; setting up recording sessions, processing audio for release, and maintaining the studio and recording equipment. He located the eventual site for YogTowers and was the person who designed its layout and unique technical design. When YogTowers was first established, he was the main auxiliary editor for the main channel, editing about 40% of the content (the rest was edited by Lewis Brindley). He edited the first few episodes of Tekkit, for example. Editors were eventually hired to take the load from Lewis and Tom, and his job fluctuated to allow him to compose and score soundtracks for the videos.
