A tweetwall lets you display only the tweets you’re interested in from everywhere on Twitter, use it to track hashtags, usernames, and keywords. The possibilities are up to you.
Clockwork’s Tweetwally is a Twitter power tool, a way to save and customize search results and present them in different formats—at a specific URL (your own, or at tweetwally.com), on a projector (at a conference, party or other gathering), or on an iPhone. Users can immediately experiment with different searches and enjoy a continuously updating stream of new information from Twitter, updated before their eyes. No registration is required — a Twitter account is all that is needed to get started.
As with all new things, there should always be an introduction. Check out Tweetwally, Part 1 and keep an eye out for the sequel, coming soon!
