Indexed isn’t a secret – it even has its own book and range of T-shirts, and has clever graphs about anything from chewing gum to virginity to dog breeding:

None of her thoughts took longer than 30 seconds to draw (I’m guessing), but it probably much longer to think about the point they’re making – the opposite of most presentation slides I see. And five minutes of browsing at Indexed is more stimulating than most one-hour presentations. Try it. After a couple of minutes you’ll be chuckling to yourself and clicking on the little envelope that emails the picture of the index card to your mates.

This might not seem very relevant if you’ve got 30 slides to deliver on process optimisation at 9am tomorrow, but you’re so wrong. Nagy’s talent is to make us work out the point she’s making by using our imagination and making our own connections. You’re much more likely to understand and to remember it afterwards.

Of course, to do this, you do need to have a point - but that’s another post.

Even if you sneak just one Indexed-inspired thought into your presentation, you’re waking your audience’s brain from its bullet-point-induced slumber. Delete your corporate SnoozePoint, go to the pub for inspiration, draw your slides with a biro on index cards for tomorrow’s process optimisation presentation when you get home at 1am, and get ready to cause a sensation. Imagine your excitement when you wake up at 8.35 on the morning of the presentation thinking, “Why is there a pile of index cards where my laptop should be?” While you might be unemployed by the end of the day, you’ll be a hero of Talknormalism.

I was trying to work out how much of my life I have spent looking at PowerPoint slides. Over the last 15 years, as an absolute minimum, I have spent at least three hours a week looking at presentations. If I spend 12 hours a day awake and get Sundays off to sit in the corner crying softly, that’s two weeks of every year. When I got involved with the exciting worlds of business and technology, sitting in room trying to work out why I am staring at pictures of two racially diverse men shaking hands wasn’t how I saw my future.

I earn some of my money presenting webcasts, where often the preparation time includes the following conversation:

Me: What does the slide with the man punching the air in front of the graph with the line going up next to the cloud inside the interlocking oval shapes balancing on the three pillars mean?
Vendor: (consults notes) It means we add value.

I’ve collected three examples of the type of slides that have been quietly making me crazy in 2009. I know the last thing you want is death by PowerPoint, but I could make that into three bullet points, maybe add a flow chart of my slow descent into fatal madness, perhaps some clip art of a doctor strapping me into the straightjacket…

First category: What the hell are you looking at? Or: why have so many slides got pictures of casually-dressed self-consciously ordinary people looking into the middle distance on them? Like this one from Cap Gemini:

If you’re wondering what the bland expression on the face of the data centre manager is meant to imply to us, I have discovered that he’s thinking these batman pyjamas are comfortable. I offer you this as evidence: recognise the expression?

(Click on the picture to buy the pyjamas. They’re top value at £22 from Great Universal. I’m hoping for commission).

Second, if you need three paragraphs to explain the diagram then you didn’t draw the bloody picture properly. Note to IBM: when you show your diagram to people and they tell you it needs some explanation or it looks like a lot of blobs with arrows coming out of them, don’t make the explanation even more opaque than the picture:

And third, what are you graphing against what? I’m talking about diagrams with the structure of something along the bottom and then two different categories up the sides and then layers of other things at the top and then lines across the middle and then some extra blobs that don’t relate to the graph in the top corners. Best done using bright colours or 3-D shapes so that no one notices.

I know the last thing you want is death by PowerPoint but this next one might just kill you. Combining elements of all the above, here’s one from Big PowerPoint itself that just makes no sense at all:

If you created this slide, I’ll enable one more business imperative for you: I’ll give you a mug if you can explain what it means to me. If the rest of you have any slides that you think deserve an unsympathetic audience, you know who to send them to.

I take comfort in the knowledge that, though I have lost months of my life looking at these crimes against communication, I’m better off than the poor sap who spent years training as a graphic designer and then ended up having to draw them.
