I recently gave my first Pecha Kucha style presentation. I’ve been wanting to for a while, ever since first seeing them at Geekup in Leeds, where the format generally involves much heckling and a trip to the bar if the subject really doesn’t grab you. For the uninitiated Pechakucha is a “lightning” presentation format of 20 slides shown for 20 seconds each giving a total presentation time of 6m40s. There’s also a variant called Ignite, mainly used by O’Reilly at their events of the same name, which is 15 seconds a slide.
The kicker is that the slides are set to automatically advance, meaning you either practice what you’re going to say meticulously, or else move the hell on before stuff starts getting thrown at you. It had been at the back of my mind to give it a go for a while and then I attended one of the first Ignite events in the UK, held at OBH in Leeds. It was a revelation, around 20 speakers in 2 hours with a couple of breaks for refreshments and networking. What made it special was the range of topics, we flitted from one idea or concept to the next and even if one didn’t appeal, you knew you were never more than 5 minutes from the next.
One speaker showed some fantastic ways in which people in Africa are using ingenuity and the materials they have to hand to build technological solutions, another spoke about the pitfalls of developing apps for the iPhone and one spoke in depth about coding something so technical that I now can’t remember even the tiniest detail. Special mention however goes to Tom Scott, who’s “My Life in 20 graphs”, had the audience roaring with laughter with a mix of Graphjam style lulz.
What they all had in common was that they were concise, punchy and in at least some measure intriguing, even when they were subjects I wouldn’t normal even consider.
So, finally I bit the bullet and pulled together a presentation of my own. I’d been asked to present my strategic plan for the year to my counterparts from our other offices and was aware it could easily turn into a bit of a stats filled yawnfest (something which I hasten to add my counterparts avoided!) and so tried to use an image led format, although eventually some more traditional bullet points did creep in.
What did I learn:
- Avoid the temptation to have more than one thought per slide, I flip flopped between thinking I wouldn’t have enough slides and having too many and crammed too much in.
- Practice several times out loud, I tried it in my head on the train to London and it’s just not the same.
- When you practice, keep yourself at a measured pace, I have a habit of speaking quickly anyway and it’s easy to almost hyperventilate as you try and get stuff out quickly.
- If you have the prep time, then write a script, learn it, then throw it away (you don’t want to be reading by rote on the night)
On the day itself, the presentation went pretty well, people seemed to like the format and the idea and I almost got a round of applause for making to the end (although I did have to cheat a little halfway through), the main problem was I had too many thoughts per slide. Even three short bullets can easily take more than 20 seconds once you’ve introduced them and added some context. Ideally slides with one picture, or one word on make life much easier. Fortunately I had a written document that accompanied the presentation, so anything I missed will still get picked up later. But at something like an Ignite event there’d be a real danger of missing out vital info.
Would I do it again, absolutely!
My top tip, should you be tempted to cram too much in though, is to sacrifice one slide half way through for a picture of a kitten. After all, you can never have too many kittens…and while people are going awwwwww, you have a chance for a breather and a drink!


Google Map Markers – 1 to 36
Bit of a niche post this one, but thought i’d share in case it saves someone else some time. I’ve been noodling around with Google Maps over the past few days on a job which started simple and then rapidly got more complex (don’t they all!)
It also pointed up some of the limitations within the My Maps version of the product. I was building a map of the UK, showing around 300 of my clients locations. I started out with a bit of a ropey spreadsheet, which after some cleanup I fed through the very useful batchgeocode.com which happily takes delimited text and chews through it geocoding the info (even if all you have is a postcode) and creating lat/long co-ordinates.
Once that’s done you can save it as a KML file and import it into Google MyMaps. That’s where the !=fun begins. For some reason MyMaps pages the results when you hit 200 markers, so from then on the map will only show one page worth of markers at a time. Not so bad on the site, but a bit sucky if you intend to embed the map (where the paging isn’t shown).
At this point I realised we’d need to wheel out the Maps API to save the day and here my technical knowledge falters a little. Particularly as not only did we need to show the 300 pins from the KML file…but each location was also allocated to one of 36 areas and each area was in one of 5 divisions.
I knew i’d be wanting something like numbered pins showing the areas and perhaps of different colours to denote the divisions. This way you get clusters of colour showing the divisions and the numbers are also clustered (more or less) into areas.
But doing all that with the API was a bit beyond my limited knowledge so I handed it over to my talented team of techies who had it worked out in very short order.
Which just left me needing to locate a set of graphics for the markers, I know there are fancy pants ways of generating them programmatically but for reasons we won’t go into I needed a folder full of PNG files.
Actually finding something to fit the bill was tricky, eventually after some hunting I hit on this post at benjaminkeen.com which had a set of markers (and a PSD file, hurrah!) from A-Z in 10 different colours.
So, for those of you searching for numbered markers instead, I present below, my version. A PSD with the numbers 1-36 (I only needed that many and I don’t love you enough to go up to 99) and the 10 colours.

May it save you a little time and effort if it can.
