Three things.

Firstly, if you tried to pick these balls up, you might do yourself a mischief. They are heavy, because the sculpture is a whole load of tennis balls bonded together, and they are fixed to a solid wooden plinth. If they were individual tennis balls, you could pick them up more easily (a few at a time, like the tennis players do).

If they were separated they probably wouldn't look as impressive, because clearly, this structure is attractive, whereas a pile of tennis balls are... well, just a pile of tennis balls.

If you tried to bounce it, you wouldn't be successful. Individual balls have a certain freedom that this cube does not. They can be hit or thrown in any direction, and you can put a spin on them. These balls have been glued together, forced into a configuration.

Several people on Twitter have asked recently for images they can use for the #blimage challenge. For the uninitiated, #blimage (blog-image) is a game we started to encourage learning professionals to blog. You are sent an image which you then have to write about, metaphorically or literally. At the end of your blog post you then challenge some of your friends with another image, of your own choice. And the challenge spreads...

The #blimage challenge was started as a bit of fun between Amy Burvall and I. We started it on July 18th and it has been growing steadily ever since with many of our friends and colleagues participating. The challenge is this: Send an image to friends in your personal learning network and ask them to write a learning related blog post about it. They then challenge their friends with an image of their choice.

It is barely a week since the fabulous Amy Burvall and I started the #blimage challenge, and we are both just a little breathless as we watch how rapidly it is catching on. The challenge was just a little fun between the two of us at first. We didn't plan for it to become a global movement, but that seems to be the way #blimage is heading. In just 6 days, almost 100 edubloggers have taken up the challenge, and have then paid it forward to their colleagues and friends.

Here's my latest contribution in the series of #blimage challenges. (Someone sends you an image and you write a blog post about learning based on it - that's the game of #blimage). This image was sent to me by Australian educator Aaron Davis (@mrkrndvs). So what do I make of it? How can I frame this image in an educational context?

It looks as though Bart Simpson is having a cup of coffee with Darth Vader (how surreal is that?).

I'm always looking for new ideas to promote blogging for teachers. For me and countless others, blogging is a very important part of professional practice, and I have written extensively about its benefits for teachers in articles such as 7 reasons teachers should blog and The truth about blogging.

In conversations recently with members of my PLN including Amy Burvall (USA @amyburvall) and Simon Ensor (France @sensor63) another method began to emerge.

I'm continuing the challenge that was featured in my last post Off the Rails. The #blimage challenge is where people send me an image/photograph and I have to write a (reasonably intelligent) learning related blog post about it. This image was sent to me by Simon Ensor, (his blog Touches of Sense is well worth reading by the way) and here is my response:

The is a photo of jigsaw puzzle pieces, which brings three things to mind about education that are key to our understanding of good pedagogy.

It so happens that my friend, colleague and fellow Edupunk from two oceans away has set me a little challenge. Amy Burvall has sent me three images, and my task is to create a learning related blog post using one of them. She calls it the #blimage challenge. I'm not one to shy away from any challenge, so I hereby present a post that incorporates all three images.

The state education system can easily be compared to a railway network.

I have been working in the field of learning technologies for almost 40 years. As you can imagine, during this time I've seen quite a few developments. Have there been any surprises along the way? Plenty. In fact my specialism never ceases to amaze me, because there is always something new to learn, some new technology, app or software tool to get to grips with, or some new theory or model that is being proposed.
