I did not get finished..., but I did post where I ended up and for 4 hours I'm pretty happy. Everything (art, design) was done in the same time frame as the development. I did have a little help from one of our devs (Scott) who looked for card art and added them to the card template. Even f i took my art time out, there was no way I was getting to anything "game like..."
I also did a timelapse so you could see where I spent my time. The timer got paused (accidentally) in the middle but I pushed it forward after we got back from lunch :)
And here's the source. There's a decent drag-drop to a slot module in there.
Oh well, it was a good exercise for sure...
