Thanks a lot.

I think, you need to understand what discrete and segmented signals are. Which 
is not very difficult, in my opinion. You only have to know what they mean 
not how they are implemented. So you don’t need a deep understanding of all 
kinds of FRP things in order to hack on Grapfruit graphics support.

Did you have a look at my e-mail conversation with Jeff Heard (in the same 
haskell-cafe thread)? He thinks about adapting the Hieroglyph 2D graphics 
library to Grapefruit. There is also the graphics implementation of classic 
Grapefruit which is for 3D graphics and OpenGL-based. These may be things, 
you want to have a look at.

This sounds very good. It’s not yet sure whether I will go to Utrecht for 
supervising Grapefruit hacking but it’s very likely that I will.

Best wishes,
Wolfgang
