Dot-S (ドッツ, styled as .S) also known as Dot-Pin is a toy, similar to a Lite-Brite, created[when?] by Japanese company Tomytec. The toys allow for the creation of pictures by placing colored pegs into holes in one or more boards. Many sets allow for the creation of various sprite characters from classic video games, with each peg representing one pixel.
