Seljalandsfoss Cloning Before/After

In my post about Sk√≥gafoss, I mentioned that I spent a few tedious hours in Photoshop cloning out tourists. This led to some questions from my friend Duncan about the time I put in to remove the tourists, which in turn put it into my head to upload this. There really were a million of […]

UX Matters

We read left-to-right. We’re trained to click left-first. Worse, the fucking unhappy path is green. I clicked this “unhappy” three times on three orders before I realized their shit. Edit: On second thoughts, this is asshole design. Make it easy for customers to leave negative responses, then use the bogus data to upsell on services.

How much would I weigh on…?

I have a morbid interest in how much I would weigh on various celestial bodies. This isn’t for everyone, but visualization of weight helps me quantify extrasolar worlds and weirdos like neutron stars. I played around with a spreadsheet yesterday to start off. I came up with a couple of functions to calculate equatorial surface […]


Ciaran at is on holdiays so I have been handling adverts for the site in his absense: It’s been a different kind of challenge to do this (you try to track down vector branding for regional companies!), although quite fun.

I learned me some Illustrator

The Ouro site doesn’t look too bad

Go check it out:

The impossible snowman

I volunteered to do the poster for an 091 Labs pub quiz that’s on later in the month. I really wanted to come back to impossible shapes after the Penrose Triangle board games poster.

New business cards!

And just in the nick of time for tomorrow’s startup event:

A Penrose Triangle is apparently hard to draw correctly

I needed one for a project, but all of the triangle vectors I found through Google were either skewed or badly-hand estimated. I guess it isn’t helped that Photoshop completely lacks inbuilt tools for centering triangles.

I want this half hour of my life back

A pretty Venn diagram that explains the Irish definition of “knacker.” It got kinda cancerous toward the end.

Irish board gaming

This is why I needed a Scrabble board.

“Scrabble” Photoshop template 100% vector. You will need to download and install the News Gothic typeface on your computer in order to make use of this template. This template includes a tile so that you may make your own letters too.

Nyan Cat family vectors (.psd)

I made these wallpapers for Caira’s iPad. I found that the quality of Nyan* resources on the Internet is awful (if I can see pixels, you’re doing it wrong), so I grabbed some reference images and made my own vectors. Click the first image to download. Enjoy!

Arrakis, home of the Spice!

Arrakis. Dune. Desert planet. Now leatherbound.

Huge cheers to Frank for the early Christmas present!

2013’s April Fool

AKA “Mark’s going back to America!” I used this letter as my base template. I grabbed the logo from Google, a “scanned white page” from Google, and copy-pasted the fold lines from the original letter. I wrote and formatted the text in Google Docs, exported it as a PDF, and overlaid the scanned page and […]

100% CSS egg

I won’t call it pretty, but it works! .egg { /* Ratio between width and height should be 1.318:1. */ width: 200px; height: 263.6px; background-color: #fff; /* curve ratio 0.75:1 */ border-top-left-radius: 170% 225%; border-top-right-radius: 170% 225%; /* Curve ratio 1.41:1 */ border-bottom-left-radius: 170% 120%; border-bottom-right-radius: 170% 120%; }

Absurdly high-resolution Minecraft grass/dirt texture

Was for a poster piece that didn’t pan out. 5600 x 5600 vector master (.PSD). Enjoy.

The TARDIS and a Dalek

Jenny asked me to produce some custom pinball apron cards for Frax’s machines. You can see some examples here. Here’s the Dalek and TARDIS from them:

All in one place, for my convenience.

They just came up in a conversation.

Using a reference image, I filled in square shapes with the appropriate colours. Enjoy. Grab it here.
