What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

It's nice to see some prototype keycaps there. But I still don't have a clear idea what profile difference between these two profiles, row by row exactly. I think it's will be clearer to get a detailed comparison between this profile and the SA profile, row by row looking at one side. like this

And those pictures of prototype could be listed here in the description page.
BTW, is there any info of which company in China is in charge of the manufacture?
R0 F row is very slightly lower than SA R1 R2 and R3 is shorter than SA R2 R4 is a little short SA R3 and R4
I think that's clear; so a medium-ish height profile from close inspection.
SA is quite a bit different: http://i.imgur.com/EZgGBdg.jpg
