I prefer the models and grid map , even for PbP, as I can add pictures to my Flickr. That works well and folks enjoyed the drama of the images.

Secret boxes, yeah, did that over a decade ago around the table. Hated having to roll dice that might mean the death of a PC, but did not want them to see their rolls. So Tupperware box with solid colour would do. Or just got them to drop the dice behind my GM screen...

Prefer dice bags to boxes (though I have a few), too encumbersome.

Whew, I got hundred of models, nae thousands and most still need painted and I not painted in 10 years or more, but strangely over the last week I been dragging them out of the dust cover dark abyss and commencing to paint. Forgot how much I enjoyed it, but one must keep an open window even if it is blowing a gale outside. Think the chemical were harming me, hence why I stopped, but don a mask, proper air ventilation (major gale ootside) and walla.
