Lewis:
I have tried it briefly on an older version - it was a very captivating experience. Unsure whether useful in terms of meditation, would need further experimentation. I will try it again on my newer hardware!
The creator Robin Arnott actually has an account here (under his full name) - I have seen him post about the software before but can't find the thread. Can't figure out how to link to a user profile but you could probably message him through the Messages tab at the top if you type his screenname 'videodreaming' into the recipient tab it should find his account. I'm sure he'd be happy to answer any questions about it.
Thanks Lewis. Please tell me how it went with your new PC.
I emailed him a few weeks back and got no reply.
