Hi Wayne,
Thank you for your kind words!
I normally don't have much to add on this forum since I'm only a hobbyist developer at best, but I wanted to introduce myself to you, and the forum, as head of marketing at Instantiations.
When your question about the logo came up, I figured I'd jump in and answer:
In short, the icon within our new logo is a simplified and abstracted hot air balloon.
Like the logo that came before it, we wanted to maintain our connection to VAST (and Smalltalk), but this time do it in a new way that felt like it had evolved -- much like VAST has been evolving and progressing for years.
The 3 rings that form the abstract balloon represent the 3 incarnations of Instantiations over the past 30 years. They all overlap to represent the continuity of company founders and employees throughout these different phases of Instantiations history. Without their efforts, Instantiations wouldn't be where it is today, and this aspect of the logo is a tribute to their accomplishments.
