I am almost ready to give birth to a project that's been incubating for ages. It's still rather sparse (or, as they say in Web 2.0 speak, 'beta'). If you take a look let me know what you think....
[Update:] Thank you for all of the positive comments! (If you have any criticism that's welcome too.) As you can probably see already, the site will be quite tutorial-heavy, especially since there are already a growing number of bento blogs. As I've written in Bento Basics, the focus of most of the bentos (I'm sure there will be some exceptions) I'll be writing about are 1) brown-rice based with a large portion of vegetables, 2) made in 20 minutes or under (with some prep work) and 2) 600 calories or under (a bit more for bigger guys). They won't be that cute - at least inside the bento box. I don't have a lot of patience for cute-fiddling in the morning. You can of course add cuteness with the bento box itself or the wrapper for the bento box.
The site is still 'beta' because I'm still ironing out some background kinks, but you can already subscribe to it and things.
Incidentally, I started to make a concerted effort to make bento earlier this year, as part of an overall 'eat healthier, dammit' thing. It's been a really positive experience health-wise and taste-wise, and as one side effect I've lost about 30 lbs (15 kg or so) since the beginning of the year. Does that give you an incentive to start making bento too? :)
