RotS-Targe that was good work picking them out - my oldest son went through a Bademon phase and marbles and the cases were being left all throughout the house .... eventually the interest passed but I would still find pieces scattered around, so one day I picked up a few of his cases and threw them into my bits box thinking they looked useful. Maybe a year later I came up with that little piece of scenery - I think I finished it maybe 2 years ago ..... I like it, it looks gritty.
