For the Astronomical Society of Australia meeting this year, we at @futuremeetings built a virtual venue with 22 (I think..!) different spaces where you can chat, watch talks, examine epic video posters, or leap off asteroid Ryugu!
This was one hell of a lot of work, but I love how it's turned out! Attendees can drop into the space via a web browser, phone app, or VR headset, so there's a super low barrier for entry.
It's online conferencing, but not as you knew it 😀 (Too cheesy? Surely not!)
