This is my favourite Twitter Client recently…”Feel On!”. It’s a Japanese app but they say English version is coming soon. This client analyses tweets in timeline and attach illustration. Really well done actually.
Of course it can’t be that accurate and attaches some strange ones which makes tweets so funny, or attaches some perfect ones which makes tweets even more better!
I don’t use it as a main client as it doesn’t display that many tweets and it doesn’t show Facebook updates, but I like opening this app…Good emotional design I think.
I made an album on FB so check it out too.
