This is the 2D Circle Graphic pack (original source) composed of 33 files that can be used in a 2D Zelda-like RPG game, for instance. It was created by Daniel Cook, from lostgarden.com. According to the author:

• The shadow tiles had a total of three levels of transparency built in so that you could get a deliciously extravagant soft shadow. The plan was to have some sweet assembly code that shifted our 8-bit palette by different amounts for each indexed shadow color. Soft shadows weren’t even a buzz word at that point.
• You could have objects on top of other objects. Instead of drawing a table tile with a candle drawn into it, the candle could be a separate object layered on top of the table.
• They were drawn in Painter 2.0 using a pressure sensitive tablet. They were my first graphics drawn in Painter. I never went back to Deluxe Paint again.
