Click the different parts of the venn diagram, and you'll be able to see what the logical connective is called, what it is in lojban, and how to make it in scratch. You can also click the invert button to change everything to it's opposite state. This will mostly add or remove an outer not to the scratch block. Some lojban connectives can be made multiple ways, for example XNOR can both be .o and na .o nai. This is shown with ".o OR na .o nai"
