                                                                     Exhibit (a)


FOR IMMEDIATE RELEASE
FEBRUARY 17, 2004

OBSIDIAN ENTERPRISES (OTCBB: OBSD) FILES PRELIMINARY PROXY MATERIALS AND INTENDS
TO SOLICIT  PROXIES IN OPPOSITION  TO NET  PERCEPTIONS'  (NASDAQ:  NETP) PLAN OF
LIQUIDATION

Obsidian  Believes that Net  Perceptions'  Board of Directors  Continues to Deny
Shareholders  the  Opportunity  to  Evaluate  and Accept  Alternatives  to Their
Proposed Plan of Liquidation

INDIANAPOLIS,  February 17, 2004 -- Obsidian Enterprises,  Inc. (OTCBB: OBSD), a
holding company headquartered in Indianapolis, announced today that it has filed
preliminary  proxy  materials with the Securities and Exchange  Commission  that
will permit  Obsidian to solicit proxies from  shareholders of Net  Perceptions,
Inc.  (NASDAQ:  NETP)  opposing  the  plan of  liquidation  proposed  by the Net
Perceptions Board of Directors.

Timothy  S.  Durham,  Chairman  and CEO of  Obsidian,  stated,  "If the  plan of
liquidation  proposed by the Net  Perceptions  Board of  Directors is a superior
alternative,  it is not at all  clear  to us why it is  necessary  for  the  Net
Perceptions  Board of Directors to maintain  anti-takeover  impediments to their
shareholders' ability to evaluate and accept alternatives. We believe it is time
for the Net  Perceptions  Board of Directors to remove its poison pill and other
anti-takeover  impediments and let the  shareholders  who have the most at stake
here determine their own destiny. After taking millions of dollars off the table
in the form of stock  sales and  compensation,  failing  to find a buyer for the
company and generally  being the people most  responsible  for Net  Perceptions'
dismal performance,  it is surprising that the management and Board of Directors
of Net Perceptions now believes they are the only people  qualified to determine
which alternative the Net Perceptions shareholders may evaluate and accept."

The identity of the  participants  in the  solicitation  (as defined by Schedule
14A) and a description of their direct or indirect  interests are included under
the  captions  "Other  Information"  and  "Schedule I -  Information  Concerning
Personals Who May Solicit  Proxies" in the preliminary  proxy materials filed by
Obsidian with the SEC today.

Obsidian filed a Registration Statement on Form S-4 and a Tender Offer Statement
with  the  Securities  and  Exchange  Commission  on  December  15,  2003 and an
amendment to each on December 17, 2003. Obsidian filed additional  amendments to
the Tender Offer Statement on December 23, 2003, and January 21, 2004.

The offer is scheduled to expire at 5:00 PM, New York City time, on February 20,
2004, unless the offer is extended.  The offer is subject to certain conditions,
including that:

     o    Net Perceptions take appropriate  action to cause their poison pill to
          not be applicable to the offer;

     o    Obsidian  be  satisfied  that  Section  203  of the  Delaware  General
          Corporation Law will not be applicable to the contemplated second-step
          merger; and

     o    stockholders  tender at least 51% of the outstanding  shares of common
          stock of Net Perceptions.

The Exchange Agent for the exchange offer is StockTrans, Inc., 44 West Lancaster
Avenue,  Ardmore,  Pennsylvania  19003.  The Information  Agent for the exchange
offer is Innisfree M&A Incorporated,  501 Madison Avenue,  20th Floor, New York,
