+ <p>Evening! Let's get right back to work.</p>
+ <p>
+ Yesterday, we figured out how to correctly convert and display
+ an image on the screen. Today,we're going to figure out storing
+ those images, loading them at runtime, and switching to another
+ image later.
+ </p>
+ <p>
+ So, first up: storing and loading the image. This is gonna need
+ me to look up how the espruino fs library works. BRB...

+ <p>
+ Well that was tremendously easy. First try baby, finally I'm not
+ completely stupid about something! We're gaming! I would take a
+ photo of the screen but I didn't change the image's position so
+ it looks exactly the same. but rest assured it is there!
+ </p>
+ <p>OK, next up, we swap images on the fly.</p>

+ <p>
+ Done! Again! Wow we're going win after win today. Apart from the
+ weird bit of artifacting in the top left of the image there,
+ but, er... I'm sure that's fine. Let's ignore it for now. We'll
+ see if it continues with other images.
+ </p>
+ <p>
+ OK, so this is actually a fair cut through the work we need to
+ do here. So let's structure the screen a bit, and add the name
+ and descriptions.
+ </p>

+ <p>
+ Hoooo boy I spent a while here huh! So much for 'live' blogging.

+ <p>
+ While I've been gone I basically drew the rest of the fucking
+ owl. Look! It's the screen from the game! Pretty much
+ completely!
+ </p>
+ <p>
+ There's some artistic license; in-game the perk description
+ displays in the same column as the image, but the available area
+ there is too small to display it readably on screen, so I've
+ bannered it at the bottom instead.
+ </p>
+ <p>
+ But yeah, we've got the basics of the screen here! The list of
+ perks, the box around the selected one, the image, the
+ description. They're all loaded dynamically from the list of
+ files on the SD card, and I've just gone in and tested the
+ reselection with a timeout, and hot damn, it works.

+ />
+ </a>
+ <p>
+ Additionally, if you're code digging, you'll see I've done a
+ bunch of reorganisation. While I was hacking before, I've gone
+ in and refactored and made all of this actually functionally
+ useful for building up the application proper.
+ </p>
+ <p>
+ Next thing, then, is input. Which hopefully, shouldn't be too
+ bad? I'll tackle that at some point over the weekend. Then it's
+ just filling the rest of the perk data (and fixing whatever is
+ wrong with the action girl image) and presto, that's a screen!

+ <p>
+ OK I lied did a tiny bit more tonight. It's some housekeeping
+ code - I wanted to make sure the images displayed centrally if
+ they were cropped to just their actual data, any rows of empty
+ pixels around them removed.
+ </p>
+ <p>
+ This turned out to be a smart decision - It saves space, it
+ looks nice, and it meant I redid the action girl icon with its
+ bit of corrupted data, a bug I would have otherwise inevtiably
+ ignored until the end. No photos right now because not much has
+ actually changed but it's good and sets us up for just
+ implementing the manual selection now.
