We do love a pretty infographic, especially personalized ones like Tweetsheet that present your Twitter data by monthly activity for the past 12 months, most retweets, geographic impact (U.S. only), best followers and favorite themes. Each bar in the total tweets chart "above ground" shows in green the chunk of tweets replied to or retweeted.

Tweetsheet will only load your last 3,200 tweets (a Twitter-API limitation), so extremely prolific users may not see a full year of data. Also, we noticed it can take a bit for all your data to load and the sections to populate. You can only create Tweetsheets for your accounts, though anyone can see a Tweetsheet the owner has shared.

Clever bonus: click the bird on the left side of your Tweetsheet and it will hop into a slingshot, Angry Birds-style. You rack up points for knocking down the bars in your chart (yes, you can hit replay and tweet your score).

Tweetsheet is a teaser product from

Investor and finance blogger Paul Kedrosky used the messages that developer Neil Kodner had retrieved from Apple's official Steve Jobs memorial site to create the tag cloud shown above.

The most prominent words are "thank," "world" and "family" along with the Mac and iPhone -- the most mentioned Apple products as Kodner explains in his post.

If only every thesis was this cool: computer engineering student Jonas Pfeil made a patent-pending throwable panoramic ball camera as his final project at the Technical University of Berlin.

All you have to do is throw the foam-padded ball in the air and its 36 fixed-focus 2 megapixel mobile phone camera modules will snap photos when the ball reaches its highest point (as measured by the ball's accelerometer). Once the ball is back in your hands, you can download the photos via USB and immediately see them as one image on your computer.

As Jonas explains on the Ball Camera website, "It can capture scenes with many moving objects without producing ghosting artifacts and creates unique images." The promotional video [ embedded above ] shows panoramic images of a city square and the great outdoors.

If you were around for the dot-com boom, you probably built a free personal homepage on Geocities, a pioneering and popular community site in the late 1990s that Yahoo bought for over $3.5B in January 1999. And you probably forgot about Geocities until just now.

But enterprising Dutch designer Richard Vijgen has now created The Deleted City, a data-visualization "map" of Geocities' neighborhoods from data the Archive Team rescued before Yahoo wiped out Geocities for good in 2009 despite pleas to save it. The Archive Team is a group of volunteers committed to "saving our digital heritage."

Is your inbox overflowing? You might want to make an email-counting t-shirt like the one Boston-based developer Chris Ball and his biophysicist wife Madeleine Price Ball put together.

The components: a t-shirt preprinted with numbers along the Y axis, an Arduino LilyPad micro-controller, LED lights, a power supply that requires one triple-A battery, conductive thread, a bluetooth dongle, and an Android phone with open-source software just for the email-counting shirt. Chris wrote the code, and Madeleine, who works on the Personal Genome Project at Harvard, did the sewing.

Flickr has just launched Photo Session so up to 10 people can look at photos together, draw on the photos and chat about them in real time from their desktop computer, iPhone or iPad.

The new Flickr app for Android has Instagram-like filters and allows sharing to Twitter, Facebook, Tumblr and WordPress.

Angels are addicted to AngelList, which, like any great startup, continues to roll out features that make finding, following, connecting with and investing in cool startups easier.

One that caught our eye -- the "best match" for an investor. As AngelList co-founder Naval Ravikant tells LAUNCH via email, "It's just showing you
