I don't know if you remember the site Ono-sendai, but that was my favourite way to browse cards on the net or just quickly search for a card for reference. That site has since gone away which is a shame. Anway, we already have a few card browsers etc. out there already, but for various reasons I wasn't happy with them and none of them felt as nice to use as Ono-sendai, so being a developer I set about learning a bunch of new front-end stuff (I'm a back-end guy) and making something that was similar in feel and really user friendly in the way I liked, built specifically for browsing the cards.
So, with that I give you http://blackat.co.uk - which hopefully will act a little bit like a digital binder for some of you.
There's a couple issues I know of and need to fix, it's not optimzed for mobile at all yet and there's also various features I'd like to add in future if I can, but I felt it was ready for letting other people give it a go, so, yeah, try it out please and let me know what you think.
Note: big props go to Alsciende of NetrunnerDB as BlacKat leverages the data API - without that I would've likely never finished. I owe you a beer!
