The project list mixes practical and playful premises: a quiz drawn from phone-album photos, a memo app that uses mirrored writing, and tools that change how app usage is displayed. AnnoyingNinja’s screen pets multiply with usage time. The latest note says the site was opened on November 13 to gather previously scattered writing and works; Social is labeled as in preparation.
