Variety of simple dividers to use in a bullet journal. Link goes directly to the photo shown. No other directions or information or links. Photo is clear and easy to sketch for visual learners. May be harder for those needing step-by-step instructions.
Peter Eisenman's Berlin/Holocaust memorial Light and Shadow. I like the way the structure of the building creates strong impressions of light and dark. Also the juxtaposition between the natural and man-made forces interests me.
