Reddit user @Let Them Fly made this image of all of the Lego Batman minifigs released from 2006-2019.
Lego enthusiast Christoph Bartneck has put together a visual catalog of all 3600+ LEGO minifigures that have been released beginning in the 1970s through 2010. What’s especially nice is the heavily discounted PDF version available from Lulu for about $25 (unfortunately, that is an Adobe Digital Editions PDF, but it easy to remove Adobe’s crap DRM).
These nice looking Lego Minifig-style crayons are handmade by a seller on Etsy. A set of 8 goes for $8 plus shipping.
Nice Lego minifig versions of a Warhammer 40K Space Marine and ODST from Instructables. Now there’s a crossover that needs to happen.
ChromeBricks.Com sells Lego minifigs and bricks that are chrome and gold plated. Like this nice C3PO minifig.
