NeoJoomla are new to me as for some strange reason I've never bumped into them before, until now.
From what I gather they're a French based company that develop themes, extensions and lots of other Joomla based goodies. The theme they are releasing this month is ideal if you're getting married as it's wedding based.
As I've not played with the theme I can't really comment on the functionality or what you get but NeoJoomla do have a theme club you can join or get more information on by visiting their website.
The demo page looks nice but you can't get around the site to see what the other pages look like but like I said, if you're getting married and want to surprise your future husband or wife, then this could be for you.
