Pin Board

Pin Board is the executive pin-impression toy, the one where you press your hand into a bed of steel pins and a copy of it stands out the other side. Here the board is a few thousand pins and your cursor is what presses them. Drag across it and pins rise in a soft-edged trail; switch to Press In and the same stroke pushes them back down. Because the brush falls off smoothly toward its edge rather than cutting off sharply, strokes blend into each other and you can build up gradual slopes rather than only flat plateaus.

The whole effect depends on lighting. Each pin is drawn larger and brighter as it rises, and casts a shadow down and to the right that lands on its neighbours, so a raised region reads as genuinely standing proud of the board. Pins ease toward their target height rather than snapping, which means a fast stroke leaves a soft wake that firms up a moment after your hand has moved on. Rendering is done by blitting a pre-baked sprite for each height level, so even a completely raised board stays smooth on a phone.

There is no picture to copy and nothing to get right. Write something, draw a face, raise the whole board and carve into it, or press Invert to swap every high pin for a low one and see your drawing as its own negative. Flatten wipes it back to a blank bed. The board keeps whatever you have drawn when you resize the window, so it survives a rotation on a phone. Free, in the browser, nothing to install.
