Easy enough to create tables for your playing...(syntax below may be wrong, but you'll get the idea)

create table X as

select rownum,        -- gives you numeric sequential data
  mod(rownum,30),      -- numeric data that cycles after 30
  trunc(rownum/30),    -- numeric data that is clustered every 30 rows
  dbms_random.random   -- for random data,
  dbms_random.random_string  -- for random strings
from any_big_table     -- eg sys.source$
where rownum < p     -- where 'p' is the number of rows you want

 etc
etc
