great! thanks. with the help of this and other nasty tricks i managed to make a simple animation:well, using ' λ' rather than lambda saves 5 chars ;)(grab(build-particles 99))(pdata-map!(λ(c)1)"c")(spawn-task(λ() (grab 2)(random-seed 1)(pdata-map!(λ(p)(vadd p(srndvec)))"p")))
maybe you could sneak in some aliases next commit.. . (define p! pdata- map!) (define v+ vadd) etc+
