Hi All,
Thanks for the various suggestions.
I got the animation working with picts.

Oh, yes: that's effectively a bitmap -> image coercion. That's probably a
better thing to put than what I did in my diff.

I've run into this before. The way we solved it was to rotate bitmaps my 0
degrees: Its silly, but it works.
So
(define (world->image p)
(rotate (pict->bitmap p))

This does look like a bug in 2htdp/universe, tho.
Looking at the universe code, it is not dealing with the case that it gets
a bitmap% object. 2htdp/image's image? predicate accepts those. Probably a
diff something along these lines is the right fix (warning, untested!)
☕ git diff .
diff --git a
(define (world->image w)
(overlay (pict->bitmap (circle w))
(empty-scene 100 100)))

Hi All,
Is there a way to use big-bang with picts?
In other words, how can I convert a pict into something that big-bang
will display?
The attempt below fails with this error:
collects/racket/private/class-internal.rkt:4387:0: send: no such method
method name: copy
