and push the blue button.
　(All characters except "><+-[]." will be ignored.
"," is not supported originally.)
　A "linear code" will appear on the downer text field.
　Then copy it, fork psyark's ---- -- ---- from cited
URL, and paste it in a line sandwiched between arrows.
e.g. "Hello, World!" in Brainf*ck
　+++++++++[>++++++++>+++++++++++>+++++<<<-]>.>++.+++++++..+++.>-.
