We have a couple of Twitter client videos for our readership today courtesy of mashable. The first video covers Twittaround and last just under a minute while the second video covers Layar and lasts just over 2 minutes.

Twittaround is an iPhone app which shows promise and shows where Tweets are coming form in an augmented reality. The app works simply enough, just start it up, point the iPhone anywhere and see if someone happens to be tweeting in the neighbourhood. Twittaround should become available when iPhone 3GS goes to iPhone 3.1.

Layar has partnered with local Twitter search provider Tweetmondo for microblogging to its client. So hit up both videos below and enjoy.
