Just watching Panicz Godek's talk at RacketCon on non-textual representations of programs. I am sure many of you here will like it. Should be on www.youtube.com/racketlang tomorrow, look for "day 2 session 3".

can you be further specific what do you like about it?

I like it. I can be specific @curious_reader. Godek's key point is about having principled rather than ad-hoc representations. What does that mean? One way to say it is that wiggle in the representation should correspond to an underlying wobble. Programming language text as interpreted by parsers and compilers generally doesn't work this way because small changes in the text generally correspond to errors.

I had to watch it at 0.75x speed!

Several presenters at RacketCon spoke very fast to cram a lot of content into the 15 minute time frame. One of the risks of pre-recorded talks.
