Nice to see everyone up so early on a Saturday morning!<br><br>Where is 2htdp/universe? I just installed the latest PLT scheme release, and I don't see anything called "universe" in the list of teachpacks that comes up when I try to add a teachpack.<br>
<br>Anyway, I'm glad to see this getting worked on. I think one of the things that Scratch got right is that it provides simple image transformations, which turn out to be very useful in constructing simple-yet-compelling games. I think having more of this stuff for drscheme will make it considerably more compelling for the younguns.<br>

1. htdp/world is deprecated, use 2htdp/universe instead.<br>
<br>
2. we consider the pinhole approach to our image library as a mistake. To solve the problem Robby is working on 2htdp/image, a replacement for the image library. When it comes out (end of semester probably) it will support rotate and other such operations, plus comparisons will be much faster.<br>

I'm playing around with the image.ss and world.ss teachpacks, and I couldn't figure out how to scale and rotate images. Are there such image transformation functions in some other teachpack?<br>
