How do you know what's waiting for you in 100 Tweets?
A glanceable Twitter client
There are many Twitter clients out there to choose among. Most if not all of them are variantions on the same theme: a cronological list of Tweets plus various ways of filtering (#hashtags, @mentions, groups, etc).
These are all good for reading through the latest activity. However, it's hard to get a quick overview of what's waiting for you. To decided of you want to read the feeds now, you actually have to go and read them. I suggest a more glanceable mode, a a way of getting a quick visual overview of all incoming Tweets (your stream, selected hastags, mentions, trends, etc). As sort of a screen saver mode for a Twitter client; I suggest something like a pond of Tweets.
Based on a simple AI where single Tweets (#hashtags, @mentions, users, public, trends, etc) get a certain amount of acceleration towards other similar Tweets while moving freely on a surface will result in a self organizing and visual overview of incoming such.
Various visual clues such as grouping, group size, movment/speed work to provide hints as to issues such as recency of Tweets (the more recent activity the more movement), number of awaiting Tweets, etc.
"Glanceability" is an interesting concept, especially in these multi-monitor modern days, and you will find more information about this use-quality in this paper (PDF) by Matthews, Forlizzi and Rohrbach.
