"John Webber, the officially appointed artist for Captain James Cook’s third voyage of discovery around the Pacific (1776-1780), along with William Ellis, surgeon’s second mate on the Discovery, provided perhaps the most comprehensive and unprecedented visual record of any of Cook’s voyages. After leaving England, Webber and Ellis drew and painted the Kerguelen Islands in the far southern Indian Ocean, and Adventure Bay in Van Diemen’s Land (renamed Tasmania in 1855), before moving on to Tonga and Tahiti, then the northwest coast of America, the Unalaska Islands and Siberia’s Kamchatka Peninsula, before returning along the coasts of Southeast Asia. The two artists made drawings and watercolour paintings of everything that came within their ambit, creating the first accurate ethnographic record of Pacific culture. Captain Cook's voyage" -
Speaking of T-shirts, here is a GREAT design by artist Mark Frauenfelder. It features his character Poppy of Lollypopland (a series of illustrations that Mark created for google). She is travelling inside the heart of a friendly star. 
There will be a "cool" public arts project in NYC for three months this summer -giant waterfalls, including one that will fall from the Brooklyn Bridge - a design of Danish artist Olafur Eliasson. This could be refreshing in the heat of the summer. I will be showing my paintings at Ad Hoc Art in July/August, so it will be fun to see this when I travel there for the show. (Thanks, boingboing )
