I've put together a simple firmware modification for the Cool-er reader that allows you to quickly apply skins/themes.
Once the modification has been applied you can re-skin the reader with your own images without having to reflash.

>> Kewl-ER <<
>> SkinMod <<

I'm not a great designer, but I've put up an example skin.

Hopefully if we have some talented designers out there we can have some really nice themes for our readers

Quick instructions:
Download the latest version of kewl-er. Unzip this and place the backdoor.sh script on your reader's internal memory (not the SD card).
Download the latest version of skinMod. Unzip this and place the skinMod.sh script next to the backdoor script.
Download an example skin (e.g. Penguins!). Rename this to skin.tgz and place it next to the backdoor script.
Disconnect your reader from your computer.
Re-boot the reader.
Just to let anyone know, I've been working on some changes to this recently.
The main page has moved to here for the kewl-er project.
skinMod is now a plugin for this - it's page can be found here.
Thanks, I like the script and it works well. I mean it works flawlessly on my Astak mentor lite with COOL-ER firmware.
Glad it's working well for you!

There are some updates planned hopefully sometime this weekend - I'll post here when they're ready.
Has anyone with some graphics skills come up with some pretty themes/skins? If so would you care to share them? I fear my graphic design skills are sadly lacking.

Hi Amy

Unfortunately not - I did a little work last weekend on a MobileRead-based theme that might appeal to more people, but I'm not much of a graphic designer either, so it's still going slowly whilst I'm juggling that with other things.

I've also got some good ideas for modifications to make it easier for people to test out their own designs, but it's still a little way off at the moment.

If you have any ideas for any designs, or even just pictures you'd like to see on your own reader let me know and I'll see what I can do.
Okay, that's slick. I'M INFESTED WITH PENGUINS! THE HORROR! It's all... Tuxey!

*ahem*

I'll see what I can do about making/finding some pretties. Ex Libris classicalpants comes to mind. Anyone fancy a mock iPad one?
I want penguins!

Unfortunately it doesn't seem to work on the December firmware The kewler and skin mods seem fine, but the skin wasn't applied, and instead I've got a skin.tgz listed in my library. I don't have the reader with me right now, but if I open that file it gives me some sort of version error.
I'll have to check it with the new firmware - I'm surprised that the .tgz file shows up in the library - will definitely need to investigate shortly.
Does the native firmware really just automatically run backdoor.sh out of the box? That's... weird and cool. And so very hackable.
