Tools by Janne Honkonen is a growing collection of small web experiments, practical utilities and deliberately odd little helpers. The collection ranges from filmmaking tools — such as a fullscreen flicker, green-screen and blue-screen simulator – to niche calculators like the Earth Hour energy-savings tool. They are built around a simple idea: sometimes a very specific problem deserves a quick, purpose-made solution.
