We recently gained permission to redistribute this Twitter icon set with an included layered vector for our JungleJar readers to download. There are 15 icons total with 3 design alterations, sizes in pixel dimensions are 212x287, 132x188, 95x130, 68x92, and 53x66.
We have a new Twitter vector here on JungleJar thanks to Maurizio Russo, who we interviewed here at JungleJar around a month ago. Mau says his inspiration for this Twitter Bird vector came via the musical artist Moby. We also have a video of the creation of Mau's Twitter Bird from sketch concept to vector visualization.
