Twitter Mosaic and TwitterSheep: See Who is Following You

Twitter is filled with ways to visualize your TwitterWorld.

Here is a mozaic of my twitter followers that I made through Twitter Mozaic:

Get your twitter mosaic here.


If you want to know something about the profiles of those who follow me, you can look at this cloud created by TwitterSheep. (Hmmmm . . . Look at all of those teachers and educators with technology)

Kind of fun to see the ingenuity that has been used to make Twitter more useful and fun to use.

I found these references along with a number of other ideas at the 10,000 words blog.

So do you use a mozaic or word cloud to see who is following you?

If not, what DO you use?

Are Screen Captures Copyrighted?

One of my students asked me a copyright question about screen captures recently that I couldn't answer.

After teaching them about how to make a screen capture and suggesting that this would be a great thing to use when creating tutorials. An educator could take screen shots of software while progressing through the software and then write accompanying instructions.

Here's the question "Aren't those screen captures copyrighted?" I didn't know the answer.

I would imagine that under fair-use guidelines, an educator could include screen captures that are used in the classroom.

The question lies in whether or not such a tutorial could be posted on the web for free distribution. At another level, what about selling the tutorial to others? Do you need to pay a copyright royalty to Microsoft if you use screen captures of Microsoft Word in a tutorial book?

What do you think?
