WikiSpaces3D

Read full description

WikiSpaces 3D is about enabling people to go places *virtually*, where they couldn't go otherwise (physically), by providing a collection of such places as 3d-scans, spaces, explorable in VR (yes, also with vr glasses). (3D-scans made with Matterport.) There are already some really cool spaces: from Boeing 747 cockpits to Egyptian tombs or the LeBron James Arena! (search for those in the app!) But why? Mainly, it's about providing educational value and making knowledge accessible: in times of pandemics, students are not able to visit interesting places like museums or galleries; but if said place has been 3d-scanned and shared on WikiSpaces, students can visit it virtually. But it's really about everyone: some of the spaces allow exclusive visits to places you could normally never go to, such as a Boeing 747 cockpit (unless your friend's friend is a pilot of course, ha), or simply places far far away. Really free? Yes absolutely! Just like Wikipedia aims to share knowledge for free, WikiSpaces does too. Building WikiSpaces has been possible only because the EU has provided generous funding (subsidies) for this project. What about user-submitted content though? All spaces are shared under the CC BY 4.0 license (read more on wiki-spaces.org/license) Supported by Europe We're glad to announce that the European Union is supporting WikiSpaces 3D with funds from the EFRE subsidies program via the German state of Saxony-Anhalt. We are truly grateful for this generous support, because otherwise, creating WikiSpaces would not have been possible. Disclaimer: WikiSpaces 3D is not affiliated with or related to Wikipedia or Matterport in any way.

See the music. Keystitch trains the skill underneath every musical skill: a clear mental picture of the keyboard, so intervals, keys, and melodies stop being abstractions and start being shapes you can see. Most music education starts a few steps too advanced — past the hidden mental machinery that lets a lucky few learn so fast. Keystitch takes the other road: short, focused drills, served a couple of minutes at a time, that build durable skill with minimal wasted effort — in an app that adapts to what you can actually do, not what a lesson plan assumes. WHAT YOU'LL DO • Hear a sequence of notes and track them on your mental keyboard — then tap the note you landed on, or just say it. • Read intervals, keys, and clefs until notation feels like moves on a keyboard and not a strange language. • Hear a phrase and sing or speak it back in solfège, graded note by note. • Practice hands-free: eyes closed, prompts spoken, answers spoken back. HOW IT WORKS • A journey that serves the right drill at the right level, two minutes at a time. • Answer by voice, by touch, or by singing — fixed-do solfège throughout. • Progress you can see: every answer feeds charts of what you know cold and what needs work. • Practice goals and streaks if you want them — and never a punishment if you don't. FREE, AND WHAT MEMBERSHIP ADDS Every drill, every level, and every mode is open to everyone. Free practice starts with a full opening hour, then four minutes a day — counted only while a question is on screen. Membership removes the time limit, and today's price is the Early Adopter price: it will go up, but if you join at it, your price stays yours for as long as you stay subscribed. Nothing leaves your device: no account, no tracking, no ads. See the privacy policy for the whole story.
