Symbols for Legacy Computing
Symbols for Legacy Computing, commonly known as SLC, are a set of symbols that were added to OWOT on October 7th 2022 for SLC and November 7th 2022 for SLC2.
Among other things, SLC characters can be used to make smoother shapes, or create the illusion of 3D objects when used in conjunction with the ability to change cell background colors. They have also been a valuable asset for scripters who want to make more photorealistic image pasters.
Artists such as JRT, AndreiXYZ, Jan Soweli Asike, Place_holdrr and Polonez have taken great advantage of SLC ever since its introduction to OWOT
SLC Test Worlds
/slc
/slc was created for users to test out the first set of SLC characters, which were implemented on October 7th, 2022. Symbols introduced in the update allowed artists to create smooth shapes that can be colored to create simplistic drawings.
/slc2
A much larger set of SLC characters were introduced on November 7th, 2022, and along with it a second test world named /slc2. SLC 2 introduced a variety of box drawing characters that allowed users to effectively replicated pixel art within OWOT.
/bcolor
Though not explicitly related to SLC, the ability to customize background colors for individual cells greatly expanded the scope of SLC art.
The test world /bcolor showcases a variety of 3D creations that can be made by combining the two features.
This update also allowed for increasingly photorealistic image pasters.
